Answer:
x = 45 MPH
Explanation:
given,
Average speed of the first half = 75 MPH
Average speed of entire ride = 60 MPH
Average speed of the second half = ?
let the average speed of the second half = x MPH
now,
average of entire ride is given as 60 mph so,


75 + x = 120
x = 120 -75
x = 45 MPH
hence, the average speed of the second half comes out to be 45 MPH.
D is the answer! Hope it helps
