Question

water is pouring into a cubiodal reservior at the rate of 60 liters per minute. if the volume of reservior is 180m3, find the number of hours it will take to fill the reservior.

Answer 1

Volume=180m3
1m3=1000 l
so, 180m3=180*1000 l
time taken to fill 60 l = 1 min
so, time taken to fill 180*1000 l=
180000/60
=3000 min I.e,3000/60 hours
50hours
