Solve for v1.


  • physics -

    (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

  • physics -

    How did you get 2.25/v1?

  • physics -

    I did the algebra, combining the two terms on the left.

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

    Add 0.50km/v1 to that

  • physics -

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

  • physics -

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