Two cars start from opposite points on a main road, which is 150 km long. Car 1 runs 25 km along the road, then takes a right turn and runs 15 km, then turns left and runs 25 km more before turning back to reach the main road. Meanwhile, Car 2, due to a minor breakdown, has only run 35 km along the main road. What is the distance between the two cars at this point?
