Question: Megan is making food for a party. She has to spend 20 minutes preparing one dish in the oven. Each dish can feed 5 people. She spends 2 hours preparing as many of these dishes as she can for the party. How many people can she feed with these dishes?
Answer: First, we need to determine the total amount of minutes available for cooking. We do this by performing 2 * 60 = 120, as there are 60 minutes in an hour. Now that we know we have 120 minutes, we then divide the preparation time into the total amount of time by performing 120 / 20 = 6 dishes capable of being made. Since each dish can feed 5 people, we find the total number of people fed by performing 5 * 6 = 30 people. The answer is 30.

Question: Jordan has a new hit song on Spotify. 3 months are left in the year, and she currently has 60,000 listens. If the number of listens per month doubles, how many listens will the song have by the end of the year?
Answer: In the first month, the song will have 60,000 * 2 = 120,000 listens. In the second month, the song will have 120000 * 2 = 240,000 listens. In the third month, the song will have 240000 * 2 = 480,000 listens. By the end of the year Jordan's song will have a total of 60,000 + 120,000 + 240,000 + 480,000 = 900,000 listens. The answer is 900000.

Question: John can read a book 60% faster than his brother. If his brother takes 8 hours to read a book, how long would it take John to read 3 books?
Answer: Reading 60% faster means John's brother takes 1 + .6 = 1.6 times as long as John to read. So John reads a book in 8 / 1.6 = 5 hours. So it would take John 5 * 3 = 15 hours to read 3 books. The answer is 15.

Question: Jordan is a hockey goalie. In the first period of a game, he blocked four shots. In the second period, he blocked twice as many shots. In the third period, he blocked three fewer than in the second period. When the game ended after the fourth period, he had blocked 21 shots in all. How many did Jordan block in the fourth period?

Let F be the number of shots Jordan blocked in the fourth period. In the second period, he blocked 2 * 4 = 8 shots. In the third period, he blocked 8 - 3 = 5 shots. In the whole game, he blocked 4 + 8 + 5 + F = 17 + F = 21 shots. Thus, Jordan blocked F = 21 - 17 = 4 shots in the fourth period. The answer is 4.
