If five people, each working 8 hours a day, can assemble 400 toys in a 5-day work week, what is the average number of toys assembled per hour per person?

To determine the average number of toys assembled per hour per person, we start with the total output and the total number of hours worked.

First, calculate the total number of hours worked by all five people over the course of a week. Since each person works 8 hours per day and they work for 5 days, the calculation for the total hours worked is as follows:

Total hours worked = Number of people × Hours per day × Number of days

Total hours worked = 5 people × 8 hours/day × 5 days = 200 hours.

Next, we need to find the average number of toys assembled per hour. The problem states that the five people assembled a total of 400 toys during that week. To find the average number of toys assembled per hour across all workers, we divide the total number of toys by the total hours worked:

Average toys per hour = Total toys assembled / Total hours worked

Average toys per hour = 400 toys / 200 hours = 2 toys per hour (for all five workers).

Now, to find the average toys assembled per hour per person, we need to divide this figure by the number of workers:

Average toys per hour per person = Average toys per hour / Number of people
