Question

A robot can complete 8 tasks in 3/5 hour. Each task takes the same amount of time.

a) How long does it take the robot to complete one task?
A) 0.075 hour
B) 0.15 hour
C) 0.375 hour
D) 1.25 hours

Answer 1

To determine how long it takes for the robot to complete one task, divide the total time (3/5 hour) by the number of tasks (8) and convert the result into hours, which comes out to be 0.075 hour or 4.5 minutes.

Step-by-step explanation:

The student is asking how long it takes a robot to complete one task if it can complete 8 tasks in 3/5 hour. To find the time taken for one task, we need to divide the total time by the number of tasks.

Time taken for one task = Total time / Number of tasks

Time taken for one task = (3/5 hour) / 8

We can convert 3/5 hour to minutes by multiplying with 60 minutes (since 1 hour = 60 minutes), which gives us:

(3/5) × 60 minutes = 36 minutes

Now we divide the 36 minutes by 8 to find the time taken for one task:

36 minutes / 8 = 4.5 minutes

To convert this back to hours, we divide by 60:

4.5 minutes / 60 = 0.075 hour

Hence, the time taken for the robot to complete one task is 0.075 hour, which is option A) 0.075 hour.
