When two bodies are moving uniformly towards each other, the distance

1.	When two bodies are moving uniformly towards each other, the distance between them decreases by 6 ms-1. If both the bodies move in the same direction with the same speed, the distance between them increases by 4 ms-1. what are the speeds of the two bodies?
Answer» u + v = 6 and u - v = 4 ⇒ 2u = 10 or, u = 5 ms^-1 2v = 6 - 4 = 2 ⇒ v = 1 ms^-1.

Answer»

u + v = 6 and u - v = 4 ⇒ 2u = 10

or, u = 5 ms^-1 2v = 6 - 4 = 2 ⇒ v = 1 ms^-1.
