The smaller bags each have 100 / 2 = 50 gold coins each. So in total, they have 50 * 2 = 100 coins. So he found 100 + 100 = 200 coins. So he finds 200 / 8 = 25 coins an hour.
The answer: 25
Reverse engineering the question: Jim spends 8 hours scuba diving. In that time he finds a treasure chest with 100 gold coins in it. He also finds 2 smaller bags that have half as much gold each. How much gold does he find per hour?


Reasoning and 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: 75

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?


The slippers are $50.00 and currently 10% off so that’s 50 * .10 = $5.00 discount. The slippers are $50.00 with a $5.00 discount which makes them 50 - 5 = $45.00. The embroidery will be $5.50 per shoe, and 2 shoes make a pair so it will cost 5.50 * 2 = $11.00. The shoes are on sale for $45.00, the embroidery will be $11.00 and the shipping is $10.00 for a total of 45 + 11 + 10 = $66.00.
The answer: 66
Reverse engineering the question: Mark wants to order a pair of slippers for his wife with her initials embroidered on top. The slippers are currently $50.00 and are 10% off. The embroidery will be $5.50 per shoe and shipping is a flat rate of $10.00. How much will the slippers cost?

Question: Sam spends sixty minutes studying Science, eighty minutes in Math, and forty minutes in Literature. How many hours does Sam spend studying the three subjects?


If the number of female adults was 50 more than the males, then there were 100 + 50 = 150 females. The total number of adults is 150 + 100 = 250. The children were twice the total number of adults, thus 2 * 250 = 500. The total number of people at the family reunion is 500 + 250 = 750.
The answer: 750
Reverse engineering the question: Alden's family invited their relatives for a family reunion on Christmas eve. There were 50 more female adults than male adults, and children were twice the total number of adults. If there were 100 male adults, how many people attended the family reunion?


He had to pay for 20 * .6 = 12 car washes. That means he had to pay 12 * 15 = $180.
