The distance traveled by car A and car B is the same

distance = speed * time

car B traveled 2 hours less than car A. At time t

60t = 75(t-2)

60t = 75t - 150

15t = 150

t = 10

so, in 10 hours, car A traveled 600 km

in 8 hours, car B also traveled 600 km

The answer is, it took car B 8 hours to overtake car A.
