A person is strolling along a moving walkway at a constant velocity of 1.00 m/s with respect to the walkway, which moves at a constant velocity of 0.50 m/s with respect to the ground. An observer on the ground is walking at a constant velocity of -0.2 m/s. What is the velocity of the person on the walkway with respect to the observer on the ground?


Answer choices are:
- 0.7 m/s
1.3 m/s
- 0.3 m/s
1.7 m/s


It would be 1.3 m/s correct?

It would be

No. It would be 1.7 m/s.

Did you add the moving velocities? Did you subtract the observer velocity?
