Two cars ‘X’ and ‘Y’ start from cities ‘M’ and ‘N’ respectively towards each other at the same time. The distance between cities ‘M’ and ‘N’ is 600 km. If cars ‘X’ and ‘Y’ are moving at speeds of 20 km/hr and 30 km/hr respectively, find the distance from city ‘M’ to the point where the two cars will meet each other.
