A robot can complete 3tasks in five sixth 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?

a) 5/18 hour

a) 3 3/5 tasks

Step-by-step explanation:

A robot can complete 3tasks in five sixth hour. Each task takes the same amount of time.

a. How long does it take the robot to complete one task?

3 tasks => 5/6 hour

1 task => x

3x = 1 × 5/6 hour

x = 5/6 ÷ 3

x = 5/6 × 1/3

x => 5/18 hour

b. How many tasks can the robot complete in one hour?

5/6 hour = 3 tasks

1 hour =>x tasks

5/6x = 1 × 3

x = 3 ÷ 5/6

x = 3 × 6/5

x = 18/5

x = 3 3/5 tasks
