Arobot can complete 8 tasks in three fifths 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) one task takes hours

B) 1 hour robot can do tasks.

Solution:

Given, A robot can complete 8 tasks in three fifths hour.  

Each task takes the same amount of time.  

We have to find the following

A.)How long does it take the robot to complete one task

From given information,

8 tasks ⇒ 3/5 hour

Then, 1 task ⇒ “n” hours

So, by chris cross method,

So, one task takes hours.

B.)How many tasks can the robot complete in one hour

So, in 1 hour robot can do in tasks.
