Assuming you sleep eight hours per day, how many hours do you have left for other activities during the week?

A. 100 hours
B. 112 hours
C. 118 hours
D. 120 hours

Answer :

After subtracting 56 hours of sleep (8 hours per day for 7 days) from the total of 168 hours in a week, you are left with 112 hours for other activities, making option b the correct answer.

The question asks for the calculation of hours left for other activities in a week if you sleep eight hours per day. To find the solution, you must subtract the total hours of sleep from the total hours in a week. Given that there are 24 hours in a day and 7 days in a week, you would start with a total of 24 hours x 7 days = 168 hours per week.

Next, you would calculate the total hours spent sleeping by multiplying 8 hours of sleep per night by 7 nights,

giving 8 hours x 7 days = 56 hours of sleep per week.

Finally, you subtract the total hours of sleep from the total hours in a week to get the number of hours left for other activities: 168 hours - 56 hours = 112 hours.

Therefore, the answer to the question is 112 hours, which is option b.
