Q: Felix can lift off the ground 1.5 times more than he weighs. Felix's brother weighs twice as much as Felix and can lift three times his weight off the ground. If his brother can lift 600 pounds, how much can Felix lift off the ground?
A: Felix's brother weighs 200 pounds because 600 / 3 = 200. Felix weighs 100 pounds because 200 / 2 = 100. Felix can lift 150 pounds because 100 x 1.5 = 150. The answer is 150.
Question: There are 400 students. 120 students take dance as their elective. 200 students take art as their elective. The rest take music. What percentage of students take music?

[Question]A camping site recorded a total of 150 campers for the past three weeks. Two weeks ago, there were 40 campers which was 10 more than the number of campers three weeks ago. How many campers were there last week?
[Answer]Three weeks ago, there were 40 - 10 = 30 campers. The total number of campers from three to two weeks ago is 30 + 40 = 70. Hence, there were 150 - 70 = 80 campers last week. The answer is 80.
Q: Gabby planted a watermelon vine, a peach tree, and two plum trees in the spring. Over the summer, the plants grew and produced fruit. She only got one watermelon to grow, but she got twelve more peaches than that, and three times that number of plums. How many pieces of fruit did Gabby get to pick that summer?
A: Gabby’s peach tree grew 12 + 1 = 13 peaches. Her plum trees grew 13 * 3 = 39 plums. Thus, Gabby got 1 + 13 + 39 = 53 pieces of fruit to pick. The answer is 53.

Q: 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?
A:
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.
