Reasoning and answer: The driving time is 480 / 60 = 8 hours. The time for breaks was 30 + 15 + 15 = 60 minutes. So she spent 60 / 60 = 1 hour for rest stops. So it took her 8 + 1 = 9 hours.
The answer: 9

He shucks 10 oysters in 5 minutes we need to know how many 5 minute units are in 60 minutes so 60 / 5 = 12 units. He can shuck 10 oysters in 5 minutes and there are 12 5 minute units in an hour so he can shuck 10 * 12 = 120 oysters in 1 hour. If he can shuck 120 oysters in 1 hour, so for 2 hours in can shuck 2 * 120 = 240 oysters.
The answer: 240
Reverse engineering the question: Bob can shuck 10 oysters in 5 minutes. How many oysters can he shuck in 2 hours?

There is 1 monitor for every fifteen students because 30 / 2 = 15. There are 120 students because 8 x 15 = 120. 60% of the lunchroom is boys because 100 - 40 = 60. There are 72 boys because 120 x .6 = 72. There are 48 girls because 120 x .4 = 48. The boys drink 72 cartons of milk because 72 x 1 = 72. The girls drink 96 cartons of milk because 48 x 2 = 96. They drink 168 cartons of milk because 72 + 96 = 168.
The answer: 168

What was the question?
Question: Patrick is half the age of his elder brother Robert. If Robert will turn 30 after 2 years, how old is Patrick now?


Reasoning and answer: The sum of the weights of the three adults is 140 x 3 = 420 pounds. The sum of the weight of the two children is 64 x 2 = 128 pounds. So the total weight of the 5 people who are in the elevator is 420 + 128 = 548 pounds. This would mean that the next person's weight must not exceed 600 - 548 = 52 pounds.
The answer: 52

Question:
Three adults whose average weight is 140 pounds went first in the elevator. Two children whose average weight is 64 pounds also went inside. If an elevator sign reads “Maximum weight 600 pounds.", what is the maximum weight of the next person to get in the elevator so that it will not be overloaded?
