Question

The relation between time and water pulled by a water pump is direct.If a pump raises.600liters 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 litres (ans)
