Answer 2

Answer:

4.5 hours

Step-by-step explanation:

Swimming pool

length=70m

breadth=44m

height=3m

So, Vol.=lbh

=9240m^3

Pipe

diameter=35cm

then , r=35/200m

and h=6m/s

So,Vol.=pi r^2h

=0.57m^3.

Now , Vol.of Pool=Vol.of pipe x time

9240=0.57t

so,t=16210seconds

=270minutes

=4.5 hours
