Question: Colin can skip at six times the speed that Brandon can. Brandon can skip at one-third the speed that Tony can. And Tony can skip at twice the speed that Bruce can. At what speed, in miles per hour, can Colin skip if Bruce skips at 1 mile per hour?
Answer: Tony can skip at twice the speed that Bruce can, for a speed of 1 * 2 = 2 miles per hour. Brandon can skip at one - third the speed that Tony can, for a speed of 2 * (1 / 3) = 2 / 3 miles per hour. Colin can skip at six times the speed that Brandon can, for a speed of (2 / 3 * 6 = 4 miles per hour). The answer is 4.
[Question]The pet store can buy a goldfish for $.25 and sell it for $.75. The owner plans to use the profits from goldfish sales to buy a new tank, which costs $100. After one week, he is 45% short of the price. How many goldfish did he sell that week?
[Answer]He is $45 short because 100 x .45 = 45. He earned $55 off goldfish because 100 - 45 = 55. He makes $.5 profit per goldfish because .75 - .25 = .5. He sold 110 goldfish that week because 55 / .5 = 110. The answer is 110.
Q: There were 20 fishermen in the lake who had cast their net to catch fish. If they caught 10000 fish in total, and 19 of them caught 400 fish each with their own net, calculate the number of fish the twentieth fisherman caught.
A: The 19 fishermen who caught 400 fish each caught 400 * 19 = 7600 fish. If they caught a total of 10000 fish, the twentieth fisherman caught 10000 - 7600 = 2400 fish alone. The answer is 2400.
Question: A Ferris wheel can accommodate 70 people in 20 minutes. If the Ferris wheel is open from 1:00 pm until 7:00 pm, how many people will get to ride?
Answer: The Ferris wheel will be open for 7:00 - 1:00 = 6 hours. In one hour the wheel can ride 60 minutes / 20 minutes = 3 times the number of riders. The total per hour riders is 3 * 70 people = 210 people. If the ride is open 6 hours * 210 people = 1260 people can ride. The answer is 1260.
[Question]While reading in bed with his wife Susan, Charlie heard a noise at the door. It was Sarah entering the bedroom with 4 friends. If there were also 8 people in the living room, how many people are in the house?
[Answer]In the bedroom, there are 1 + 1 = 2 people in the house (Charlie and Susan). Sarah and four friends then entered, a total of 4 + 1 = 5 people. Together with Charlie and Susan, there are now 5 + 2 = 7 people in the bedroom. Since there are 8 more people in the living room, the total number of people in the house is 8 + 7 = 15. The answer is 15.
