Question

Water is pouring into a cubiodal reservoir at the rate of $60litresperminute$. if the volume of reservoir is $108m^3$, find the number of hours it will take to fill the reservoir.

Answer 1

Given, Rate of flow of water $=60$ litres/minute.

Volume of the tank $=108m^3.$

$1m^3=1000$ litres

$108m^3=108\times 1000=108000$ litres.

Time taken to fill the complete tank.

$=108000/60$

$=1800$ minutes.

$=1800/60$ hours.

$=30$ hours.

$\therefore$ The tank will be filled completely in $30$ hours.
