In 2 hours, 3 plumbers can repair 10 taps. How much time will the 3 plumbers take to repair 12 taps?

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

*i think

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
