Answer 1

Answer:

1 hour 12 minutes are required to fill the same tank with 5 similar types of pipes.

Step-by-step explanation:

6 pipes are used for filling a tank in 1 hour

So 5 pipes will fill x in (6/5)hours

That is 1.2 hours or 1 hour 12 minutes

Here we have used unitary method to find the values
