Question

An engine pumps out $950litres$ of water in a minute. How much time will it take to pump out $13,96,500litres$of water?

Answer 1

Given:

Amount of water an engine can pump in a minute = $950litres$

Time is taken to pump out $950litres$ of water = $1minute$

Time is taken to pump-out $1litresofwater=\frac{1}{950}min$

Time is taken to pump out $13,96,500$ liters of water

= $13,96,500\times \frac{1}{950}minute$

= $1,470minutes$

Hence,$13,96,500litres$ of water will be pumped in $1,470minutes.$
