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
