Q: Grayson drives a motorboat for 1 hour at 25 mph and then 0.5 hours for 20 mph. Rudy rows in his rowboat for 3 hours at 10 mph. How much farther, in miles, does Grayson go in his motorboat compared to Rudy?
A: Grayson first travels 1 * 25 = 25 miles. Then Grayson travels 0.5 * 20 = 10 miles. Grayson travels a total of 25 + 10 = 35 miles. Rudy travels 3 * 10 = 30 miles. Grayson travels 35 - 30 = 5 miles more than Rudy. The answer is 5.
Question: Tom plants a tree that is 1 year old and 5 feet tall. It gains 3 feet per year. How old is it when it is 23 feet tall?
Answer: It has grown 23 - 5 = 18 feet. So it is 18 / 3 = 6 years older. That means it is 6 + 1 = 7 years old. The answer is 7.
[Question]Jasmine gets off of work at 4:00 pm. After that, it will take her 30 minutes to commute home, 30 minutes to grocery shop, 10 minutes to pick up the dry cleaning, 20 minutes to pick up the dog from the groomers and 90 minutes to cook dinner when she returns home. What time will she eat dinner?
[Answer]Her errands include a 30 min commute and 30 min grocery shopping, 10 min for dry cleaning and 20 min to grab the dog for a total of 30 + 30 + 10 + 20 = 90 minutes. Her errands took 90 minutes and she has another 90 minutes of cooking for a total of 90 + 90 = 180 minutes of chores / errands. 60 minutes are in 1 hour and she has 180 minutes of work so that's 180 / 60 = 3 hours. She is off of work at 4:00 pm and has 3 hours of errands / chores so she won't be able to eat until 4 + 3 = 7:00 pm. The answer is 7.
Q: Jim decides to buy mayo in bulk. He can buy 1 gallon of mayo at Costco for 8 dollars. At the normal store, a 16-ounce bottle costs $3. How much money does he save by buying the gallon container?
A: A gallon is 1 * 128 = 128 ounces. So he needs to buy 128 / 16 = 8 of the small bottles. That would cost 8 * 3 = 24 dollars. So he saves 24 - 8 = $16. The answer is 16.
Question: Two years ago, Jared was twice as old as Tom. If Tom will be 30 in five years, how old is Jared now?
Answer: Tom will be 30 in 5 years so now he is 30 - 5 = 25. 2 years ago Tom was 25 - 2 = 23. At that time, Jared was twice as old as Tom so Jared was 23 * 2 = 46. Two years have since passed so Jared is now 46 + 2 = 48. The answer is 48.
