A robot can complete 5 tasks in 7/10 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

7/10 = .7(60) = 42 minutes to complete 5 tasks

7/10/5 = 7/50 =14/100 = 0.14 hour = .14(60) = 8.4 minutes to complete 1 task

in one hour, the robot completes

10/7 x 5 = 50/7 = 7 1/7 tasks
