    Given :   A traffic school class has three parts. In the first part, a film is shown that takes one fifth of the class time. In the second part, the instructor lectures for 70 minutes. In the final part, a test is given that

    takes one third of the class time.

    To find : The duration of the traffic school class

    Solution:

    Let say Duration of the traffic School Class = 15T  Minutes

    First Part =  one fifth of the class = (1/5) 15T  = 3T  Minutes

    Second Part = 70 Minutes

    Third Part = one third of the class time = (1/3) 15T = 5T Minutes

    Total Time = 3T + 70 + 5T  = 8T + 70 Minutes

    8T + 70 + 15T

    => 70 = 7T

    => T = 10

    => 15T  = 150

    The duration of the traffic school class is 150  minutes
