[Question]Lara is a contestant on a fun game show where she needs to navigate an inflated bouncy house obstacle course. First she needs to carry a backpack full of treasure through the obstacle course and set it down on the other side, which she does in 7 minutes and 23 seconds. Second, she needs to crank open the door to the obstacle course so she can go back through, which takes her 73 seconds. After she gets through the door she traverses the obstacle course again and makes it out faster without the backpack, in 5 minutes and 58 seconds. How many seconds total does it take her to complete the obstacle course?
[Answer]It takes Lara 7 minutes and 23 seconds to make it through the obstacle course the first time. 7 minutes x 60 seconds per minute = 420 seconds + 23 seconds = 443 seconds to get through the first part of the obstacle course. The second stage of the obstacle course she completes in 73 seconds + 443 seconds = 516 seconds. It takes 5 minutes and 58 seconds for Lara to get through the obstacle course the second time. 5 minutes x 60 seconds per minute = 300 + 58 seconds = 358 seconds. Combined, it takes Lara 516 + 358 seconds = 874 seconds for Lara to run the whole obstacle course. The answer is 874.

Q: There were 60 women at the party, and three-fourths of these women were married and brought their husbands with them to the party. If 3/4 of the men at the party were single, how many people attended the party?
A: 60 x 3 / 4 = 45 females are married which means there are also 45 married males. If 1 / 4 of the men are married, which represents 45 men, then 4 * 45 = 180 is the total number of men who attended the party. Thus, there are a total of 60 women and 180 men, or a total of 60 + 180 = 240 people at the party. The answer is 240.
Question: A typical tournament of tennis has 4 rounds. There are 8 games in the first round, 4 in the second round, 2 in the third round and 1 during the finals. If each game requires new tennis balls, and on average each game uses 5 cans of tennis balls, how many tennis balls in total are used at the end of the tournament if each can has 3 tennis balls?
Answer:
There are a total of 8 + 4 + 2 + 1 = 15 games of tennis in a typical tournament. If 1 game uses 5 cans of tennis balls, then 15 games would use 15 * 5 = 75 cans of tennis balls. If 1 can of tennis balls has 3 balls, then 75 cans would have 225 balls. The answer is 225.
