O.500km/v1+3.50km/2v1=0.250h

**drwls**, Monday, November 22, 2010 at 12:46am(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

**John**, Monday, November 22, 2010 at 12:58amHow did you get 2.25/v1?

**drwls**, Monday, November 22, 2010 at 1:02amI did the algebra, combining the two terms on the left.

3.50km/(2v1) = 1.75km/v1

Add 0.50km/v1 to that

**John**, Monday, November 22, 2010 at 1:07amThanks I don't know I could forget that. Is this like algebra?

**drwls**, Monday, November 22, 2010 at 6:54amYes. You need to do some algebra to get the answer. You don't need any physics.
