Solve for v1.

(2.25 km)/v1 = 0.25 h
v1 = 9 km/h
h would have to have dimensions of time for this to make any sense. I assume the "h" means hours in this case

How did you get 2.25/v1?
- physics - drwls, Monday, November 22, 2010 at 1:02am
I did the algebra, combining the two terms on the left.
3.50km/(2v1) = 1.75km/v1
Add 0.50km/v1 to that

Thanks I don't know I could forget that. Is this like algebra?

Yes. You need to do some algebra to get the answer. You don't need any physics.
