Q#6 (b)

One pipe filling the pool in 5 hours = 1.25 times

If the second pipe is used with the same intensity of pressure for filling then in the given fives hours filling cspacity gets double

So two pipes filling a pool with the same pressure in 5 hours =

2 x 1.25 (times) = 2.50 times

Here the two pipes with the same capacity of filling the pool divided by 5 hours

5 hours /2.50 = 2 hours for the pipes with 1.25 times

Slower pipe will take 5 hours for 1 time filling the pool as hour with slower capacity.

Right I think ?? maths is difficult.
