What are the speeds of two objects if, when they move uniformly towards each other, they get 4 m closer in each second and when they move uniformly in the same direction with the original speeds, they get 4 m closer each 10 s?

A

2.8 m/s and 12 m/s

B

5.2 m/s and 4.6 m/s

C

3.2 m/s and 2.1 m/s

D

2.2 m/s and 1.8 m/s

Text Solution

Verified by Experts

The correct Answer is:
D
`v_(A) + V_(B) = 4m//s, v_(A) - v_(B) = (4)/(10)m//s`
