Two placer A And B2 Are 120km apart from each othe on a highway.a car start from A And another from B At the same time.if they move in the same direction.they meet in 6hrs and in opposite direction they meet in 1hrs 12mins,find the speed of each car?
since distance = time * speed,
6(a-b) = 120
6/5 (a+b) = 120
Now just solve for a and b
