Q: Tony exercises every morning by walking 3 miles carrying a 25-pound backpack, then he runs another 10 miles without the backpack. If he walks at a speed of 3 miles per hour and runs at a speed of 5 miles per hour, how many hours each week does he spend exercising?
A: Tony walks 3 miles at 3 miles per hour for 3 / 3 = 1 hour. Tony also runs 10 miles at 5 miles per hour for 10 / 5 = 2 hours. Thus, each day he exercises for 1 + 2 = 3 hours. Over the course of one week, he exercises for 3 * 7 = 21 hours. The answer is 21.
Question: Abigail has a report due tomorrow which needs to be 1000 words in length. Abigail can type 300 words in half an hour. If she has already written 200 words, how many more minutes will it take her to finish the report?
Answer: She needs to type an additional 1000 – 200 = 800 words. In one minute she can type 300 words / 30 = 10 words. It will take her 800 / 10 = 80 more minutes to finish typing the report. The answer is 80.
[Question]Ivan has a piggy bank that can hold 100 pennies and 50 dimes. How much, in dollars, does Ivan have if he has filled his two piggy banks with those coins?
[Answer]Ivan has 50 x 10 = 500 cents from the 50 dimes in his one piggy bank. So, he has a total of 100 + 500 = 600 cents in one of his piggy banks. Since 100 cents is equal to 1 dollar, then Ivan has 600 / 100 = 6 dollars from one of his piggy banks. Therefore, Ivan has a total of $6 x 2 piggy banks = $12 from his two piggy banks. The answer is 12.
Q: Cortney is downloading some files to her computer. Her internet speed is 2 megabits per minute. If she can download the files one at a time and the files she is downloading have the size of 80 megabits, 90 megabits, and 70 megabits. How many hours will it take for her to download all of it?
A: The first file will take 80 / 2 = 40 minutes to download. The second file will take 90 / 2 = 45 minutes to download. And the third file will take 70 / 2 = 35 minutes to download. So, it will take 40 + 45 + 35 = 120 minutes for all the files to download. Therefore, the total hours she will have to spend to download all the files is 120 / 60 = 2 hours. The answer is 2.
Question: John had $200. He gave 3/8 of his money to his mother and 3/10 to his father. How much money did John have left?
