A cyclist Amoves with a speed 3.0 m/s to the left(with respect to the road). A second cyclist, B, moves on the same straight-line path as A with a relative velocity of 1.0 m/s with respect to A. What is the velocity of B with respect to the road. And a third cyclist has a relative velocity with respect to A of -2.0m/s. Whatis the velocity of C with respect to the road?
*What does it mean when it says "What is the velocity of B with RESPECT TO THE ROAD" and "A third cyclist has a RELATIVE VELOCITY WITH RESPECT TO A OF -2.0 m/s. WHAT IS THE VELOCITY OF C WITH RESPECT TO THE ROAD", specifically the capatilized parts
And also how do you solve the questions

"with respect to the road" means that you can assume the road is a straight line and that all cyclists are on the same road either moving in the same direction opposite directions. If you did not assume that, calculating relative velocities would be quite complicated.
B is going 4m/s on the road
and C is going 1m/s

A is going 10.8Km B could be 7.6 or 14.4 Km C is in front they will be going 3.6Km and if behind then 18 Km That my answer then again I could be wrong, but I think the question does not tell You in what order they are in.

Assume you are at rest, what velocity do other vehicles move with respect to you ?
