Let x = rate of first hose.
.8x = rate of second hose (it is 20% slower) so it is 80% of the first hose rate.
With both hoses the rate would be 1.8 x which completes the job in 16 4/11 minutes.
multiplying the rate by time shows the capacity of the oil tank as 29.45
to accomplish with the second hose along would be 29.45/.8=36.8 minutes.
That doesn't seem to just right, but you might get some ideas from it.
