In one minute- Bill would wash 1/6 of car and Andy 1/8-Hence together in one minute they would wash(1/6+1/8) 14/48 of car. Therefore they would take 48/14 minutes or 24/7 or 3min26sec to wash the complete car.

6 minutes...... Bill would get so ticked off at Andy for being so darned slow that he'd figure that it would be eaier to do it himself.
