You walk with a velocity of 2 m/s north. you see a man approaching you, and from your frame of reference he has a speed of 3 m/s to the south. what is the velocity of the man from the frame of reference of a stationary observer? (2 points)

The answer to this question would be: 1m/s

When you are walking to the north with 2m/s velocity, the stationary object(velocity=0m/s) will look like moving south at 2m/s velocity. That happens because the relative distance between you and the object is reduced by 2m/s in both conditions. In this question, the man seems like have 3m/s velocity. The real velocity should be:
3m/s - 2m/s = 1m/s

My answer is opptionc, just check with anyone else
