Question

a robot can complete 5 tasks in 3/10 hour. Each task takes the same amount of time. How long does it take the robot to complete one task?

Answer 1

Since we know 1/10 of 10 is 6 minutes, 3/10 is 18 minutes. Now, we can do 18/5, which you will get 3 3/5 minutes per task. To know the amount of seconds, 1/5 of a minute is 12 seconds. 12 times 3 equals 36. So therefore, it would take three minutes and thirty six seconds. Please give brains list answer is this explanation helped.

Answer 2

Time taken to complete one task by the robot is 3.6 minutes

Time taken by robot to complete five tasks = 3/10 hours

So by unitary method we can say that the time taken for  one task =

$\dfrac{3}{10} \times \dfrac{1}{5} = \dfrac{3}{50} \; hours$

   $\dfrac{3}{50}\; hours = 0.06 \; hours$

Converting hours into minutes we can write

1 Hour = 60 minutes

so 0.06 hours = $60\times 0.06 \;minutes$ = 3.6 minutes
