Question

A robot can complete 5 tasks in 2/3 hour. Each task takes the same amount of time.

a. How long does it take the robot to complete one​ task?
b. How many tasks can the robot complete in one​ hour?

Answer 1

A. 8 Minutes

B. 7.5 Tasks

Explanation:

A. Since 2/3 of an hour is 40 minutes. We can divide 40 by 5 to get the answer of 8 minutes per task.

B. An hour is 60 minutes. So 60 divided by 8 minutes would be 7.5 Tasks.

Answer 2

5 tasks = 2/3 hour.

1 task = 2/3 hour /5 = 2/15 hour.

How many tasks can the robot complete in one hour?

1 hour / (2/15 hour/task) = 15/2 tasks = 7.5 tasks.
