- Homework Statement
- I am not sure if my working out is correct because I have 2 values

- Relevant Equations
- d=vt

Two students run around a 400m sport field. A goes anticlockwise (i.e., 1-2-3-4-1) while Bruns clockwise (i.e., 1-4-3-2-1). Students A and B can run 400 m in 75.0 s and 65.0 s,respectively.

Students A and B should meet at some point of the run. Where do they meet? Assume the cross-over position is P. What is their relative velocity at position P.

My working out:

Lets first find the relative velocity, which going to be 12

t=d/v

400/12 = 33.33... seconds

d = 5.33 * 33.33 = 177.67m

d= 6.67 * 33.33 = 222.32m

Now, whats confusing me is that I have two values and I am not sure what to do with them.

Any help will be appreciated :)
