Answer:
16 hours
Explanation:
Given: There are 4 people in your crew.
Each spent 4 hours of laying sod.
To find the person hours, we have to multiply the number of people (4) by the amount of hours each person spent (4).
Total number of hours = Number of persons * Number of hours spent
Total number of hours = 4 x 4 = 16 hours
Therefore, the total amount of hours is 16.
