    Answer:

    68.57 miles per hour

    Explanation:

    Given data

    Distance= 120 miles

    Time= 1 hours 45 minutes

    Let us convert the time all to hours

    45 minutes to hours is 0.75 hours

    Hence the time in hours is

    =1+0.75

    =1.75 hours

    Also, the expression for the speed is given as

    Speed= distance/time

    Substitute

    Speed= 120/1.75

    Speed= 68.57

    Hence the speed is 68.57 miles per hour
