It takes 18 hours to fill a pool
WebLet V be the volume of the pool. Then the flow rate of the hoses are r A = V 4, r A + r B = V 3. Hence the rate of B alone is r B = ( r A + r B) − r A. Hence the time taken to fill the pool with hose B is V r B = V ( r A + r B) − r A. Substitute the values for r A, r B to get the answer.
