Teena's speed - 55 mph
Joe's speed - 40 mph
They are driving in same direction, hence the resultant speed will be 55 - 40 = 15mph
Now Teena is 7.5 miles behind and needs to go 15 miles ahead of Joe.
So total distance needs to be covered - 7.5 + 15 = \(22.5 miles\)
22.5 miles will be traveled with the speed of 15 mph
Time taken = \(\frac{Distance}{speed}\) = \(\frac{22.5}{15}\) = 1.5 hours = 90 mins
Answer D
