[Question]Harry is joining a marathon that's why he practices and varies his workouts from day to day. He ran 10 meters per hour on Monday. From Tuesday to Thursday he ran 50% faster than on Monday. Then on Friday, he ran 60% faster than he ran on Thursday. How fast did Harry run on Friday?
[Answer]Harry ran 10 x 50 / 100 = 5 meters per hour faster on Tuesday to Wednesday. So he ran 10 + 5 = 15 meters per hour from Tuesday to Thursday. Then on Friday, he ran 15 x 60 / 100 = 9 meters per hour more. Therefore, he ran 15 + 9 = 24 meters per hour on Friday. The answer is 24.

[Question]We the People has 17 cows. Happy Good Healthy Family has two more than three times the number of cows We the People has. If their cows are taken to a ranch to graze together, how many cows will be in the ranch altogether?
[Answer]Three times the number of cows We the People has is 3 * 17 = 51 cows. Happy Good Healthy Family has two more than three times the number of cows We the People has, a total of 51 + 2 = 53 cows. If the cows are taken to a ranch to graze together, their total will be 53 + 17 = 70 cows. The answer is 70.
Q: Nurse Missy is attending to the needs of 12 patients in her hospital ward. Most of her patients require standard care, but one-third of her patients have special dietary requirements, which increases the serving time by 20%. At dinner time, she brings each patient their meal. It takes 5 minutes to serve each standard care patient. How long does it take, in minutes, for Missy to serve dinner to all of her patients?
A: Nurse Missy has 12 * (1 / 3) = 4 special needs patients. She has 12 - 4 = 8 standard care patients. Special needs patients take 20% longer to serve, which means serving takes 1.2 * 5 = 6 minutes per patient. To serve dinner to all of her standard care patients, it will take 5 * 8 = 40 minutes. To serve dinner to all of her special needs patients, it will take 6 * 4 = 24 minutes. In total, it will take 40 + 24 = 64 minutes to serve dinner to all of her patients. The answer is 64.
Question: Oliver is working out in a gym. On Monday he worked out for 4 hours, and the next day for 2 hours less. On Wednesday he decided to work out twice as much as on Monday. On Thursday the gym was closed, so Oliver needed to exercise at home which took twice as much time as on Tuesday. How many hours in total have Oliver worked out during these four days?
Answer:
On Tuesday, Oliver worked out for 4 - 2 = 2 hours. On Wednesday he decided to work out twice as much as on Monday, so for 2 * 4 = 8 hours. On Thursday, at home, Oliver trained twice as much as on Tuesday, so for 2 * 2 = 4 hours. In total Oliver trained for 4 + 2 + 8 + 4 = 18 hours. The answer is 18.
