Question

8 pipes can fill a tank in 2 hours. how long will 5 pipes take to fill same tank​

Answer 1

Answer:

1 hour

and 10 mins will be 70mins

So 8 pipes take 70 mins to fill a tank.

The more number of pipes, the less time it takes to fill a tank. In this case, the tank is a constant as there is only 1 tank needed to be filled.

y=k/x

let y be time

let x be number of pipes

70=k/8

k= 70(8)

k= 560

y=560/5

y= 112mins

y= 1hr 52mins

Answer 2

Answer:

•Time taken by 8 pipes to fill the tank= 2 hours.

•Time taken by 1 pipe to fill the

tank = 2×8=16 hours

So, Time taken by 5 pipes = 16/5 = 3.2 hours.
