Question

A robot can complete 8 tasks in 5/6 hour. each task takes the same amount of time.

Answer 1

Answer:

A robot can complete 8 tasks in hour = $\frac{5}{6}$

A robot can complete 1 task in hour = $\frac{\frac{5}{6}}{8}$

A robot can complete 1 task in hour = $\frac{5}{48}$

So,  it take $\frac{5}{48}$ hours the robot to complete the task

A robot can complete tasks in  $\frac{5}{6}$ hour = 8

A robot can complete tasks in  1 hour = $\frac{8}{\frac{5}{6}}$

                                                           =$9.6$

So,  the robot complete 9 tasks in one hour.

Answer 2

5/6 hour = 5/6 × 60 = 300/6 = 50 minutes

8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes

a. robot completes task in 6 1/4 minutes

b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6

robot can complete 9 tasks in one hour
