A and B are two points 150 km apart on a highway.two cars start from A and B at the same time if they move in the same direction they meet in 15 hours but if they move in the opposite direction they meet in 1 hour find their speeds

Answer 1

If the speeds are a and b, then under suitable assumptions, since distance = speed*time,

15a+150 = 15b
a+b = 150

now just solve for a and b.

Answer 2

A=70
B=80
