[Question]In three baseball games this week, eighty people watched the second game while 20 fewer people watched the first game than the second game. Then 15 more people watched the third than the second game. If there were a total of 200 people who watched the games last week, how many more people watched the games this week than last week?
[Answer]This week, 80 - 20 = 60 people watched the first game. While 80 + 15 = 95 people watched the third game. A total of 80 + 60 + 95 = 235 people watched the games this week. Thus, 235 - 200 = 35 more people watched the games this week than last week. The answer is 35.
Q: Michelle had some leftover cans of silly string from her birthday party. She split them among Roger and 3 of his friends. Then Roger decided to give 2 of his cans to his brothers so that he now has 4 for himself. How many cans of silly string did Michelle have to start with?
A: Roger originally had 4 cans of silly string + 2 can he gave to his brothers = 6 cans. Since his friends received the same amount as Roger did originally, 3 friends x 6 cans of silly string = 18 cans. Michelle started with 6 cans that went to Roger + 18 cans that went to his friends = 24 cans of silly string. The answer is 24.
Question: Apple can run at a rate of 3 miles per hour. Mac can run at a rate of 4 miles per hour. In minutes, how much faster will Mac run a 24 mile race?
Answer:
First find how fast each runs. Apple = 24 miles / 3 miles per hour = 8 hours. Mac = 24 miles / 4 miles per hour = 6 hours. Mac runs 8 hours - 6 hours = 2 hours faster. 1 hour = 60 minutes, so, Mac runs faster by 2 hours * 60 minutes = 120 minutes. The answer is 120.
