Answer 2

Option: c is the correct answer.

He completes 1.25 of inspection in 1 hour.

Explanation:

Robert can complete 10 inspections in 8 hours.

Unit rate is defined as how much of something per unit of something else.

He completes 10 inspection in 8 hours.

or we can say that in 8 hour he completes 10 inspections.

So, in 1 hour he completes: 10/8 inspections=1.25 inspections.

Hence, option:c is correct.

He completes 1.25 of inspection in 1 hour.
