20 min How long will it take f only 5 people of
the some type are used ​

Answer 1

Answer:

Step-by-step explanation:

Let the Time Taken Required Be "x".

Pumps                Time Taken(in minutes)

    6                      1 hr 20min = 60min + 20min = 80min    [1 hour = 60 min]

    5                                      x

Cross Multiply And We Get,

    6x = 5 x 80

Therefore,

      x = 5 x 80/6

We Get,

      x = 96 mins

Now Let's Convert Into Hours,

    As,  1 hour = 60 minutes

           

Therefore,

     x = 96 minutes = 1 hour 36 minutes

Thus, time taken to fill the tank by 5 pumps is 96 minutes or 1 hour 36 minutes.
