1. The problem statement, all variables and given/known data Basically I was given a table displaying speed of a vehicle, thinking distance (distance it takes for driver to react) and braking distance. I am told to find an equation relating speed of vehicle and overall distance (overall distance = thinking distance + braking distance). 3. The attempt at a solution Using graphing software, I've managed to find an approximate equation relating speed and thinking distance, as well as an equation relating speed and braking distance. The equations are : For speed vs thinking dist., y = (16/3)x, where y is speed of vehicle and x is thinking distance and For speed vs braking dist., y = 13(x^0.5), where y is the speed of vehicle and x is braking distance Is there any way I can find an equation for speed versus overall distance using these 2 equations that I've obtained?
