Question

Three taps pour 7000 L of water into a reservoir in 6 hours. In how many hours do 5 taps equal to the previous ones discharge 8000 L of water?

Answer 1

Hey!

3 taps --- 7000 liters --- 6 h
5 taps --- 8000liters --- x h
***
5 --- 7000 --- 6
3 --- 8000 --- x
***
5 * 7000 * x = 3 * 8000 * 6
35000x = 144000
x = 144000/35000
x = 4.11h

4 h 6 min 36 sec
