The pool is 15m wide and 40m long and should be filled with water to a height of 2.5m. The water flows at a rate of 400 hl per hour. How many hours will the pool be filled to the required height?

Correct answer:

t =  37.5 h

Step-by-step explanation:

a=15 m b=40 m c=2.5 m V=a b c=15 40 2.5=1500 m3 v=400/10=40 m3/h t=V/v=1500/40=37.5 h
