When two bodies move toward each other with constant speeds the distance between them decreases at the rate of 6m / sec. If they move in the same direction the distance between them increases at the rate of 4m/sec. Then their speeds arePhysics A. 5m/s, 1m/s B. 3m/s, 3m/s C. 6m/s, 1m/s D. 4m/s, 2m/s
