Mario and Kenneth work in a car wash station. The time that Mario takes in washing a car alone is 20 minutes less than the time that Kenneth takes in washing the same car. If both of them work together in washing the car, it will take them 90 minutes. How long will it take each of them to wash the car?



Kenneth=50 mins
mario=40 mins
