Two buses start from the opposite points of a main road, 150 kms apart. The first bus runs for 25 kms and takes a right turn and then runs for 15 kms. It then turns left and runs for another 25 kms and takes the direction back to reach the main road. In the meantime. due to a minor breakdown, the other bus has run only 35 kms along the main road. What would be the distance between the two buses at this point?
