Question

Mrs.Green wants to make some toys for a store. She starts working at 8AM and stops at 12PM everyday. The store needs 120 toys and requires Mrs. Green to make them in three days. What must be her average rate of toys made per hour?

Answer 1

10 toys per hour

Explanation:

Given that she starts working at 8AM and stops at 12PM everyday, that means she works

= 12 - 8

= 4 hours daily

If the store needs 120 toys and requires Mrs. Green to make them in three days, the total time available for her to make the number of toys required

= 4 * 3

= 12 hours

Hence her average rate of toys made per hour

= 120/12

= 10 toys per hour
