[Question]In preparation for the upcoming Olympics, Rita's swimming coach requires her to swim a total of 1,500 hours. Rita has already completed 50 hours of backstroke, 9 hours of breaststroke, and 121 hours of butterfly, but she is unhappy with her inconsistency. She has therefore decided to dedicate 220 hours every month practicing freestyle and sidestroke. How many months does Rita have to fulfill her coach’s requirements?
[Answer]So far, time spent practicing backstroke, breaststroke, and butterfly is 50 + 9 + 121 = 180 hours. Since Rita’s must swim 1500 hours, the freestyle and sidestroke practice sessions will take 1500 - 180 = 1320 hours. Rita will practice for 220 hours / month, meaning she will meet her coach’s target in 1320 / 220 = 6 months. The answer is 6.
Q: A craftsman makes 16 jars. This is exactly twice the number of clay pots he made. If each jar has 5 marbles and each clay pot has three times as many, how many marbles are there?
A: 16 jars are exactly twice the number of clay pots made by the craftsman, meaning there are 16 / 2 = 8 clay pots. If each jar has 5 marbles, the total number of marbles in the jars is 5 * 16 = 80. Each of the clay pots also has 3 * 5 = 15 marbles. The total number of marbles in the 8 clay pots is 15 * 8 = 120. There are a total of 120 + 80 = 200 marbles. The answer is 200.
Question: Diane bakes four trays with 25 gingerbreads in each tray and three trays with 20 gingerbreads in each tray. How many gingerbreads does Diane bake?
Answer: Four trays have 4 x 25 = 100 gingerbreads. And three trays have 3 x 20 = 60 gingerbreads. Therefore, Diane bakes 100 + 60 = 160 gingerbreads. The answer is 160.

[Answer]If the total number of points was 112, and Layla won with 70 points, Nahima scored 112 - 70 = 42 points. Layla scored 70 - 42 = 28 more points than Nahima. The answer is 28.
Q: Paul, Amoura, and Ingrid were to go to a friend's party planned to start at 8:00 a.m. Paul arrived at 8:25. Amoura arrived 30 minutes later than Paul, and Ingrid was three times later than Amoura. How late, in minutes, was Ingrid to the party?
A: If the party was planned to start at 8:00 am, Paul was 8:25 - 8:00 = 25 minutes late. If Paul was 25 minutes late, Amoura was 25 + 30 = 55 minutes late. If Ingrid was three times late than Amoura was, she was 3 * 55 = 165 minutes late. The answer is 165.
Question: Martin is casting three bells for the church's belfry. The first bell takes 50 pounds of bronze, the second bell is twice the size of the first bell, and the third bell is four times the size of the second bell. How much bronze does he need total?
Answer:
First find the size of the second bell: 50 pounds * 2 = 100 pounds. Then find the size of the third bell: 100 pounds * 4 = 400 pounds. Then add the amount of bronze used for each bell to find the total: 100 pounds + 400 pounds + 50 pounds = 550 pounds. The answer is 550.
