Two cars are driving toward each other

Two cars are driving toward each other. The first car is traveling at a speed of 75 km/h, which is 25% slower than the second car's speed. If the distance between the cars is 1050 km, how many hours will it take until the two cars meet?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
