Answer:

2h 24 min

Step-by-step explanation:

The number of plumbers is constant. We can therefore choose to omit them from our calculations.

10 taps can be done in 2h

What about 12 taps.

This calls for cross multiplication.

(12*2)/10

this gives you 2.4 hrs

to get your answer in standard time format...

(4/10)*60

giving you 24

final answer is 2h 24 min
