The distance between 2 towns is 300 km.two car start simultaneously from these towns and move towards each other.the speed of one car is more than the

other by 7 km/h.if the distance between the cars after 2 hours is 34 km.find the speed of cars


Let the speeds of cars be x, y (x>y). Difference between speeds is x-y=7. In two hours net distance travelled by both the cars is 2x+2y. Separation after two hours is 300-2(x+y)=34. Solving above two equations, you have the speeds to be x=70 and y=63.
