It would take 150 minutes to fill a swimming pool using 5 taps.
a) How many minutes will it take to fill the pool if only 3 of the taps are used?

Complete the following.
b) An assumption being made in my working is that all the taps are flowing at the same time.

a) Assuming all taps flow at the same rate, the time is inversely proportional to the number of taps. Using 3/5 of the total taps will take 5/3 of the time required when all taps are used.

For 3 taps, the time is ...

(5/3)(150 minutes) = 250 minutes
