On a long stretch of east-west road, A and B are two points such that B is 350 km west of A. One car starts from A and another from B at the same time. If they move towards each other, then they meet after 1 hour. If they both move towards east, then they meet in 7 hrs. The difference between their speeds, in km per hour, is?

Answer: 50

Solution:
Let the speeds of Cars are v and u. then, v+u=350———–1)
and v-u=350/7=50———-2)
So required difference in speeds=50 km/hr
