Emptying a Tank

Two pumps of different sizes, working
together, can empty a fuel tank in 5 hours.The larger pump
can empty this tank in 4 hours less than the smaller one. If the
larger pump is out of order, how long will it take the smaller
one to do the job alone?

Is this a MathCAD? The symbol := is familiar.
