A robot can complete 8 tasks in 5/6 hour.

A: What is the unit rate for hours per task?

B: What is the unit rate for tasks per hour?

Given:

8 tasks

5/6 hours total

Unit rate per task:

5/6 hours : 8 tasks = 5/6 * 1/8 = 5/48 or 0.10 hours per task

0.10 hours x 60 minutes/hour = 6 minutes per task.

Unit rate per hour:

8 tasks : 5/6 hours = 8 * 6/5 = 48/5 = 9.60 tasks per hour or rounded to 10 tasks per hour.
