You are driving to the grocery store at 12.2 m/s. You are 193.0 m from an intersection when the traffic light turns red. Assume that your reaction time is 0.790 s and that your car brakes with constant acceleration. How far are you from the intersection when you begin to apply the brakes?

physics 
bobpursley,
distancetraveled=velocity*reactiontime.
subtract that from the initial distance to the light.
