Alex is on a cross-country bike trip. After starting this morning, he manages an average speed over flat ground of about 20 miles per hour. Four and a half hours later, the road started to incline upwards enough that he could only manage 12 miles per hour. Two and a half hours later, though, the road declined downhill and was able to mostly coast at 24 miles per hour. Unfortunately, he only got to enjoy this for one and a half hours before he punctured a tire. He had forgotten to pack a repair kit, so he had to walk his bike the rest of the way to the next town.

Question: If the next town was 164 miles from where he started this morning, how far did Alex have to walk?
Answer: Alex traveled at 20 miles per hour for 4.5 hours, so 20 * 4.5 = <<20*4.5=90>>90 miles on flat ground.
He traveled 12 miles per hour uphill for 2.5 hours, so 12 * 2.5 = <<12*2.5=30>>30 miles uphill.
He traveled downhill 24 miles per hour for 1.5 hours = 24 * 1.5 = <<24*1.5=36>>36 miles downhill.
Before his tire punctured, he traveled 90 + 30 + 36 = <<90+30+36=156>>156 miles.
So as the next town is 164 miles from where he began, Alex had to walk for 164 - 156 = <<164-156=8>>8 miles.

Jacob can write twice as fast as Nathan. Nathan wrote 25 letters in one hour.

Question: How many letters can the two write in 10 hours together?
Answer: Since Nathan writes 25 letters in an hour, Jacob writes 25*2 = <<25*2=50>>50 letters in an hour.
Together, they write 50+25 = <<50+25=75>>75 letters in an hour,
In 10 hours, they'll write a total of 75*10 = <<10*75=750>>750 letters

In 21 hours, a heating plant consumes 7 liters of fuel.

Question: How much does it consume in 90 hours?
Answer: Let x be the consumption in 90 hours.
We have: 21/7 = 90/x because the heating plant always consumes fuel at the same rate
Multiplying both sides by 7x, we get 21x = 90 * 7
This can be simplified to 21x = 630
So, the consumption in 90 hours is x = 630 / 21 = <<630/21=30>>30 liters.

George picks 22 by the end because 12 + 10 = <<12+10=22>>22
Billy picks 66 by the end because 36 + 10 = <<36+10=46>>46
In total they picked 68 because 22 + 46 = <<22+46=68>>68
On average they picked 34 because 68 / 2 = <<68/2=34>>34

A store is having an anniversary sale. A tub of ice cream costs $2 less than its original price of $12 and the juice is sold at $2 for 5 cans.

Question: How much will you pay if you buy two tubs of ice cream and 10 cans of juice?
Answer: The price of a tub of ice cream is now $12 - $2 = $<<12-2=10>>10.
So the two tubs of ice cream amount to $10 x 2 = $<<10*2=20>>20.
There are 10/5 = <<10/5=2>>2 sets of 5 cans of juice.
Thus, you will pay $2 x 2 = $4 for the 10 cans of juice.
Therefore, you will pay a total of $20 + $4 = $<<20+4=24>>24.

The school nurse must conduct lice checks at the elementary school. She must check 26 Kindergarteners, 19 first graders, 20 second graders, and 25 third graders.

Question: If each check takes 2 minutes, how many hours will it take the nurse to complete all the checks?
Answer: The school nurse must check a total of 26 Kindergarteners + 19 first graders + 20 second graders + 25 third graders = <<26+19+20+25=90>>90 students in all.
If every check takes 2 minutes, it will take 90 students x 2 minutes = <<90*2=180>>180 minutes.
There are 60 minutes in one hour, so it will take 180 minutes / 60 = <<180/60=3>>3 hours to complete the checks.

Lily got a new puppy for her birthday. She was responsible for feeding the puppy 1/4 cup of food three times a day for two weeks starting tomorrow. For the following 2 weeks, Lily will feed him 1/2 cup of food twice a day. She has fed him 1/2 cup of food today.

Question: Including today, how much food will the puppy eat over the next 4 weeks?
Answer: 1 week has 7 days so 2 weeks will have 2*7 = <<7*2=14>>14 days
The puppy will eat 1/4c three times a day so .25*3= <<.25*3=.75>>.75 cups per day
The puppy will eat .75 cups of food a day for 14 days for a total of .75*14 =<<.75*14=10.5>>10.5 cups
The puppy will then eat `.5 cup of food twice a day so .5*2 = <<.5*2=1>>1 cup per day
The puppy will eat 1 cup of food a day for 14 days for a total of 1*14 = <<1*14=14>>14 cups per day
She has already fed him .5 cup of food and he will eat 10.5 cups and another 14 cups for a total of .5+10.5+14 = <<.5+10.5+14=25>>25 cups of food

Question: If Birgit kept the same pace, how many minutes would it take her to go 8 kilometers?
Answer: Minutes spent hiking = 3.5*60 = <<3.5*60=210>>210 minutes
Average speed = 210 minutes/ 21 km = <<210/21=10>>10 minutes/km
Birgit is 4 minutes/km faster = 10 - 4 = 6 min/km
It would take 6*8 = <<6*8=48>>48 minutes to go 8 km
Birgit would take 48 minutes to travel 8 kilometers.

Jonathan enjoys walking and running for exercise, and he has three different exercise routines. On Mondays, he walks at 2 miles per hour. On Wednesdays, he walks at 3 miles per hour. And on Fridays, he runs at 6 miles per hour. On each exercise day, he travels 6 miles.

Question: What is the combined total time, in hours, he spends exercising in a week?
Answer: On Mondays, he walks 6 miles at 2 miles per hour, for a length of 6/2=<<6/2=3>>3 hours.
On Wednesdays, he walks 6 miles at 3 miles per hour, for a length of 6/3=<<6/3=2>>2 hours.
And on Fridays, he runs 6 miles at 6 miles per hour, for a length of 6/6=<<6/6=1>>1 hour.
The combined total time he spends exercising in a week is 3+2+1=<<3+2+1=6>>6 hours.

Greta worked 40 hours and was paid $12 per hour. Her friend Lisa earned $15 per hour at her job.

Question: How many hours would Lisa have to work to equal Greta's earnings for 40 hours?
Answer: For the 40 hours worked, Greta earned a total of 40 * 12 = $<<40*12=480>>480.
To find how many hours Lisa has to work to earn $480, we divide 480 / 15 = <<480/15=32>>32

Elroy decides to enter a walk-a-thon and wants to make sure he ties last year's winner's cash collection. Last year, walkers earned $4 a mile. This year walkers earn $2.75 a mile.

Question: If last year's winner collected $44, how many more miles will Elroy walk than last year's winner to collect the same amount of money?
Answer: Last year's winner walked 11 miles because 44 / 4 = <<44/4=11>>11
Elroy has to walk 16 miles to collect $44 because 44 / 2.75 = <<44/2.75=16>>16
Elroy will walk 5 more miles because 16 - 11 = <<16-11=5>>5
