Consider the Q and A. Q: Based on a 2008 study, children 6–11 years old spend 45 minutes each day watching television. How many hours do these children watch television in 2 weeks if they are allowed to watch television 4 days a week?
A: 6
What is the step-by-step reasoning process?
Step-by-step reasoning process: The children watch a total of 45 x 4 = 180 minutes in a week. In hours, this is equal to 180 / 60 = 3 hours a week. Thus, these children watch 3 x 2 = 6 hours in two weeks.

Consider the Q and A. Q: Joel is 5 years old and his dad is 32 years old. How old will Joel be when his dad is twice as old as him?
A: 27
What is the step-by-step reasoning process?
Step-by-step reasoning process: The difference in age between Joel and his dad is 32 - 5 = 27 years. When you double this gap in years, you have 27 x 2 = 54. When his dad is 54, Joel will be 54 / 2 = 27 years old.

Consider the Q and A. Q: It takes Polly 20 minutes to cook breakfast every day. She spends 5 minutes cooking lunch. She spends 10 minutes cooking dinner 4 days this week. The rest of the days she spends 30 minutes cooking dinner. How many minutes does Polly spend cooking this week?
A: 305
What is the step-by-step reasoning process?
Step-by-step reasoning process: Polly spends 20 * 7 = 140 minutes cooking breakfast. She spends 5 * 7 = 35 minutes cooking lunch. She spends (10 * 4) + (30 * 3) = 130 minutes cooking dinner. Therefore, she spends 140 + 35 + 130 = 305 minutes cooking this week.

Consider the Q and A. Q: Patrick is half the age of his elder brother Robert. If Robert will turn 30 after 2 years, how old is Patrick now?
