Question: A dog barks 30 times per minute. If 2 dogs bark 30 times per minute, how many times will they have barked after 10 minutes?
Answer: There are 2 dogs and they each bark 30 times per minute so together they bark 2 * 30 = 60 times per minute. 2 dogs bark a combined total of 60 times per minutes, after 10 minutes they will have barked 60 * 10 = 600 times. The answer is 600.
[Question]Bob can shuck 10 oysters in 5 minutes. How many oysters can he shuck in 2 hours?
[Answer]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 is 240.
Q: Jason's stove catches on fire. Buying a replacement will cost $1200 and fixing the damage to the wall behind it will cost 1/6th as much. How much does he spend in total?

Question: Prejean's speed in a race was three-quarters that of Rickey. If they both took a total of 70 minutes to run the race, calculate the total number of minutes that Rickey took to finish the race.
Answer: Let's say Rickey took t minutes to finish the race. If Prejean's speed in the race was three - quarters that of Rickey, and Rickey took t minutes to finish the race, the time that Prejean took to finish the race is 3 / 4 * t = 3 / 4t. Together, Rickey and Prejean took t + 3 / 4t = 70. They took 1 3 / 4 t hours = 70 to finish the race. This is 7 / 4t = 70. t = 70 * 4 / 7. The time that Rickey took to finish the race is t = 40 minutes. The answer is 40.
[Question]Toby is in a juggling contest with a friend. The winner is whoever gets the most objects rotated around in 4 minutes. Toby has 5 baseballs and each one makes 80 rotations. His friend has 4 apples and each one makes 101 rotations. How many total rotations of objects are made by the winner?
[Answer]Toby gets 400 full rotations because 5 x 80 = 400. His friend get 404 rotations because 4 x 101 = 404. The winner rotated 404 objects because 404 > 400. The answer is 404.
