Question

A robot can complete 3 tasks in 4/5 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. 16 minutes.
b. around 3.5 tasks.

Answer 2

Hello! I can help you with this!

a. Okay. So, it takes 4/5 hour (48 minutes) to complete 3 tasks. To find the answer, divide the amount of time by the number of tasks. 48/3 = 16. It takes the robot 16 minutes to complete 1 task.

b. So it takes 16 minutes to complete 1 task. To solve this, we can do 60/16. 60/16 is 3.75 or 3 3/4 in simplest form. But you can’t exactly count 3/4 as one task. The robot can only complete 3 tasks in one hour.
