[Question]Ralph is going to practice playing tennis with a tennis ball machine that shoots out tennis balls for Ralph to hit. He loads up the machine with 175 tennis balls to start with. Out of the first 100 balls, he manages to hit 2/5 of them. Of the next 75 tennis balls, he manages to hit 1/3 of them. Out of all the tennis balls, how many did Ralph not hit?
[Answer]Out of the first 100 balls, Ralph was able to hit 2 / 5 of them and not able to hit 3 / 5 of them, 3 / 5 x 100 = 60 tennis balls Ralph didn't hit. Out of the next 75 balls, Ralph was able to hit 1 / 3 of them and not able to hit 2 / 3 of them, 2 / 3 x 75 = 50 tennis balls that Ralph didn't hit. Combined, Ralph was not able to hit 60 + 50 = 110 tennis balls Ralph didn't hit. The answer is 110.

Question: A soccer team had 24 players prepared for a soccer game. The first half saw 11 players start the game with 2 substitutions made. In the second half, the team made twice as many substitutions as it made in the first half. How many players on the team did not play that day?
Answer: With two substitutions, 11 + 2 = 13 players from the team played the game in the first half. In the second half, the team made twice the number of substitutions it made in the first half, a total of 2 * 2 = 4 substitutions. The total number of players who played the game is 13 + 4 = 17. If the soccer team had 24 players prepared for the soccer game, the number of players who did not play the game is 24 - 17 = 7 players. The answer is 7.
[Question]An airplane took a trip along the Eastern Coast of the USA. During the trip, the plane hovered in Mountain time for 3 hours, Central time for 4 hrs, and Eastern time for 2 hrs. The next day it took 2 more hours to hover in each of the places it passed through the previous day. Calculate the total time it took the plane to hover over Mountain time, Central time, and Eastern time in the two days.
[Answer]The total time it took to hover over the Mountain and the central time is 3 + 4 = 7 hours. If it hovered further to the Eastern time zone, it took a total of 7 + 2 = 9 hours to cover the whole trip. The next day, it took 2 more hours to cover each of the places it passed through the previous day, taking a total of 2 * 3 = 6 hours. The total time it took on the second day to cover the distance it covered the previous day is 9 + 6 = 15 hours. In total, the train took 15 + 9 = 24 hours to hover over the places in the two days. The answer is 24.
Q: A convenience store sold 100 bags of chips in a month. In the first week, 15 bags of chips were sold. In the second week, thrice as many bags of chips were sold. There was an equal number of chips sold in the third and fourth week. How many chips was each sold in the third and fourth week?
A: In the second week, 15 x 3 = 45 bags of chips were sold. So there was a total of 45 + 15 = 60 bags of chips sold on the first and second week. Thus, a total of 100 - 60 = 40 bags of chips were sold on the third and fourth week. Therefore, 40 / 2 = 20 bags of chips were each sold on the third and fourth week. The answer is 20.
Question: Isabel loves to run in the forest and she does it within a circuit that is 365 meters long. She runs the circuit 7 times in the morning and runs it 3 times in the afternoon. How many meters does Isabel run during a week?
Answer:
In the morning she runs 7 * 365 = 2555 metres. In the afternoon she runs 3 * 365 = 1095 meters. In one day, afternoon and morning, she runs 2555 + 1095 = 3650 meters. In a week, she runs 7 * 3650 = 25550 meters. The answer is 25550.
