Question

The volume of a reservoir is 216m3. Water is poured into it at the rate of 30L per minute how many hours will it take it fill the reservior

Answer 1

Given that volume of the reservoir = 216m^3.

We know that 1m^3 = 1000 litres.

                        216m^3 = 216 * 1000

                                      = 216000 liters.


Given that Rate of water pouring per minute = 30 liters.

Therefore the time is taken to fill the reservoir = $\frac{216000}{30}$

                                                                              = 7200 minutes

                                                                              = $\frac{7200}{60}$

                                                                              = 120 hours.


Hope this helps!
