Question

The relation between time and water pulled by a water pump is direct. If a pump raises 600 liters water in 45 minutes, how much water it will raise in 1 hour.​

Answer 1

Solution:

As the unit of times are different, so first we make them the same.

1 hour=60 minutes

Time : Volume of water

45 : 600

60 : x

As the proportion is direct, so

45/60 = 600/x

x=600×60/45

x=2400/3

x=800 liters
