In order for that to happen, at some point they would have had to pass each other along the way, and when they passed each other neither would have traveled 810km . (Velocity and Acceleration of a Tennis Ball). So the rate at which, so 2 times x-- maybe I'll do that in yellow-- 2 times x, x is 0.6 so it's going to be 1.2 times dx dt, so that's negative 30 miles per hour.
