Question: Sofia and her mother go to the grocery store and buys 10kgs of oranges to be used in their home for the week. While at the store, Sofia's father calls and says they're to add 5 more kgs since their neighbor also wanted some supplies. When they reach home, they estimated that for the next coming two weeks they'll have to buy twice as many oranges each week for the supplies to be enough. What the total quantity of oranges they would have bought after the three weeks.
Answer: Step-by-step reasoning process: For the first week, they bought 10 + 5 = 15kgs. For the next week, they bought twice the quantity of oranges which is 2 * 15 = 30kgs. For the next two weeks, the total quantity of oranges bought is 30 * 2 = 60 kgs. The total quantity for the three weeks is 60 + 15 = 75 kgs.
So the answer is 75.

Question: Three planes are going to the same place but each has a different number of passengers. The first plane has 50, the second had 60, and the third has 40. An empty plane can go 600 MPH, but each passenger makes it go 2 MPH slower. What is their average speed?
Answer: Step-by-step reasoning process: The first plane goes 100 MPH slower than empty because 50 x 2 = 100. The first plane goes 500 MPH because 600 - 100 = 500. The second plane goes 120 MPH slower because 60 x 2 = 120. The second plane goes 480 because 600 - 120 = 480. The third plane goes 80 MPH slower because 40 x 2 = 80. The third plane goes 520 MPH because 600 - 80 = 520. The total speed is 1500 because 500 + 480 + 520 = 1500. Their average speed is 500 because 1500 / 3 = 500.
So the answer is 500.

Question: Percy swims 1 hour before school and 1 after school 5 days a week. He swims 3 hours on the weekend. How many hours of swimming does he do over 4 weeks?
Answer: Step-by-step reasoning process: He swims 1 hour before and after school for a total of 1 + 1 = 2 hours. He swims 2 hours a day for 5 days for a total of 2 * 5 = 10 hours. He also swims an additional 3 hours on the weekend so 10 + 3 = 13 hours. Over a course of 4 weeks, at 13 hours per week, he swims 4 * 13 = 52 hours.
So the answer is 52.
