Question: Kenny wants to make sure he does more jumping jacks every week than he did the week before. He recorded that last week he did 324 total jumping jacks. On Saturday of this week, he looks at his records and sees that on Sunday he did 34. On Monday he did 20. On Tuesday he skipped a day. On Wednesday he did 123. On Thursday he did 64. On Friday he did 23. How many does he have to do on Saturday to make sure he beats last week's number?
Answer: He has already done 264 this week because 34 + 20 + 123 + 64 + 23 = 264. If he does 60 he will have done as many as last week because 324 - 264 = 60. He has to do 61 on Saturday because 60 + 1 = 61. The answer is 61.
[Question]Luke is planning a trip to London and wants to see how long it will take him to travel there. He decides that he will take a bus to the town center, walk for 15 minutes to the train center, wait twice this long for the train to arrive, and then take the 6-hour train ride to London. If Luke's entire trip takes him 8 hours, how many minutes does his bus ride take?
[Answer]Removing the time of the train ride from the journey shows that his trip to get on the train took him 8 hours 6 hours = 2 hours. Converting this time into minutes shows that getting to the train took 2 hours * 60 minutes / hour = 120 minutes. Waiting for the train to arrive took twice as long as his walk, so 15 minutes * 2 = 30 minutes. This means that his bus ride must have taken 120 minutes 30 minutes - 15 minutes = 75 minutes. The answer is 75.
Q: Calvin is a bug collector. In his collection, he has 12 giant roaches, 3 scorpions, half as many crickets as roaches, and twice as many caterpillars as scorpions. How many insects does Calvin have in his collection?
A: With half as many crickets as roaches, he has 12 / 2 = 6 crickets. With twice as many caterpillars as scorpions, he has 3 * 2 = 6 caterpillars. In total, he has 12 + 3 + 6 + 6 = 27 insects in his bug collection. The answer is 27.
Question: The electricity price in Coco's town is $0.10 per kW. Coco's new oven has a consumption rate of 2.4 kWh (kilowatt-hours). How much will Coco pay for using his oven only if he used it for a total of 25 hours last month?
Answer: If Coco used his oven 25 hours last month and its energy consumption is 2.4 kW per hour, then we consumed a total of 25 * 2.4 = 60 kW on his oven last month. If the price of electricity is $0.10 per kW, then 60 kW would cost = $0.10 * 60 = $6. The answer is 6.
[Question]Tim drops a ball off the roof of a 96-foot tall building. The ball bounces to half the height from which it fell on each bounce. How high will it bounce on the fifth bounce?
[Answer]On the first bounce, it will reach a height of 96 / 2 = 48 feet. On the second bounce, it will reach a height of 48 / 2 = 24 feet. On the third bounce, it will reach a height of 24 / 2 = 12 feet. On the fourth bounce, it will reach a height of 12 / 2 = 6 feet. On the fifth bounce, it will reach a height of 6 / 2 = 3 feet. The answer is 3.
