Oil tank and pipes

The underground oil tank can be filled by two oil pipelines. The first is filled in 72 hours and the second in 48 hours. How many hours from the moment when first pipeline began to fill the oil is it necessary to start filling it with the second to fill in 1 and 1/2 day?

Correct answer:

t =  12 h

Step-by-step explanation:


t/72 + (36-t)•(1/72+1/48) = 1

3t = 36

t = 12
