Question: Michael is stuck in an elevator that is slowly moving to the bottom floor. The elevator needs to move down 20 floors to reach the bottom. It takes 15 minutes for the elevator to travel down the first half of the floors. The elevator then takes 5 minutes per floor to travel down the next 5 floors. It then takes 16 minutes per floor for the elevator to finish traveling down the final 5 floors. In hours, how long did it take for the elevator to reach the bottom?
Answer: Over 5 of the floors, it takes the elevator 5 floors * 5 minutes per floor = 25 minutes to lower. Over the final 5 floors, it takes the elevator 5 floors * 16 minutes per floor = 80 minutes to lower. So in total, the elevator takes 15 minutes in the first half + 25 minutes in the next five floors + 80 minutes in the final five floors = 120 minutes to lower to the bottom. This is the same as 120 minutes / 60 minutes per hour = 2 hours. The answer is 2.
[Question]Billy has four horses. Each one eats 4 pounds of oats, twice a day. How many pounds of oats does he need to feed his horses for 3 days?
[Answer]At each feeding Billy serves 4 horses x 4 pounds of oats / horse = 16 pounds / feeding. Each day Billy uses 16 pounds of oats / feeding x 2 feedings / day = 32 pounds of oats / day. Triple that amount to find the amount of oats needed to feed the four horses for three days: 32 pounds of oats / day x 3 days = 96 pounds. The answer is 96.
Q: Roger had a 6-hour drive planned out. He didn't want to listen to music so he downloaded several podcasts. The first podcast was 45 minutes long. The second podcast was twice as long as that. The third podcast was 1 hour and 45 minutes long. His fourth podcast is 1 hour long. How many hours will his next podcast have to be to fill up the full 6 hours?
A: The second podcast was twice as long as the first so 2 * 45 = 90. 1 hour is 60 mins. So his 1 hour and 45 min podcast is 60 + 45 = 105 minutes long. So far he has downloaded 45 + 90 + 105 + 60 = 300 min. If he converts 300 min to hours then he has 300 / 60 = 5 hours of podcasts downloaded. He has 5 hours of podcasts and his drive is 6 hours so he will need 6 - 5 = 1 more hour of podcasts. The answer is 1.

[Question]Mark wants to have a water balloon fight with his friends. He goes to the store to buy balloons and sees that they sell small bags for $4, medium bags for $6 and extra large bags for $12. He has $24 and wants to get the most balloons as possible. If the $4 bags contain 50 balloons, the $6 bags contain 75 balloons and the $12 bags contain 200 balloons, what is the greatest number of balloons he can buy?
[Answer]He can buy 6 small bags because 24 / 4 = 6. These give him 300 balloons, because 6 x 50 = 300. He can buy 4 medium bags because 24 / 6 = 4. These give him 300 balloons because 4 x 75 = 300. He can buy 2 extra large bags because 24 / 12 = 2. This gives him 400 balloons because 2 x 200 = 400. 400 is the most he can buy because 400 is greater than 300. The answer is 400.
