Question

A pump can fill a 1800 kL tank in one hour. How long would it take to fill a 90 kL tank?

Answer 1

Step-by-step explanation:

1 hour = 1800 kg

1 min = 1800 / 60 = 30 kg

90 kg = 90 / 30 = 3 min

Answer 2

Given :

Time to fill 1800 kL tank = 1 hr

To find :

Time to fill a 90 kL tank .

Solution :

We know , one hour has sixty (60) minutes .

Time to fill 1800 kL tank = 1 hr = 60 min

time to fill 1 kL tank = ( 60 / 1800 ) min

then , time to fill 90 kL tank = ( 60 / 1800 ) * 90 min

                                              = 3 min

It would take 3 minutes to fill a 90 kL tank .
