This question is taken from Direct and Inverse Proportion

According to that when x increases with y direct proportion takes place and when x/y decrease and y/x increase Inverse Proportion takes place

Step-by-step explanation:

As per the question :

Time taken if only 6 pipes are used= 1hr 20min ( 80min)[as 1hr is 60 min]

Time taken if only 5 pipes are used=x

As per the question if x decrease y also decreases that means it is in direct proportion

FORMULA FOR DIRECT PROPORTION =xy= k

6/80=5/x

= 6x=80×5

=96 min
