Velocity and Acceleration help needed

  1. Sep 30, 2007 #1
    Runner A is initially 6.0 km west of a flagpole and is running with a constant velocity of 9.0 km/h due east. Runner B is initially 5.0 km east of the flagpole and is running with a constant velocity of 8.0 km/h due west. What will be the distance of the two runners from the flagpole when their paths cross?

    Write an equation for each runner, solve for time, then plug time into one of the equations to get distance. Use the same method for the other problem you posted.
