- Homework Statement:
- A wagon is carrying a long, wooden beam with constant speed in one direction. If we go along with the wagon, we find, that the wooden beam is 15 steps long (it takes 15 steps to go along the beam while the wagon is moving). If we go against the wagon, we find that the beam is 10 steps long. How many steps long is the beam?

- Relevant Equations:
- v=s/t

v_g+v_e=15/t_1

v_g-v_e=10/t_2

v_g=s/(t_1-t_2)

But there are too many unknowns. What am I missing?

v_g-v_e=10/t_2

v_g=s/(t_1-t_2)
