Question

One fill pipe A is 10 times faster than second fill pipe B. If B can fill a cisten in 55 mins, then find the time when the cistern will be full if both fill pipes are opened together.​
plz ans guys...​

Answer 1

A is 10 times faster than B

B alone can fill a cistern in 55 minutes

A is 55*10=550

Converting into minutes 550/60

A can fill a cistern in 9 minutes 17 seconds

If both are opened at a time then time taken to fill a cistern is =

9.17+55/2=32 minutes 08 seconds
