Question

It takes Patty one-third of an hour to wash a car and half that time to dry off a car. How long will it take her to wash and dry 6 cars?

2 Answer

  • For washing, he takes = 1/3h = 60/3 = 20 min.
    For drying = 10 min.

    So, for 1 car, he takes = 20 + 10 = 30 min.

    Now, for 6 cars, he takes = 30 * 6 = 180 min = 180/60 = 3 hours

    In short, Your Answer would be 3 hours

    Hope this helps!
