Answer 1

Answer:

1 hr 20 mins = 80 mins

Here , we will apply the concept of inverse variation

Now just imagine

if you are doing a task alone then you will take a lot of time to do that. And when you are accompanied by a group of people , you take less time to do it. Same is the concept with pipes.

1 pipe will take a lot of time to fill a tank. Whereas 6 pipes will take less time to fill the same tank. Hence, the proper way to solve this -

6 pipes----->80 mins

1 pipe------->80×6 mins

5 pipes----->480/5 mins = 96 mins = 1 hr 36 mins

thus answer is 1 hr 36 mins. Plz mark this answer the brainliest
