## Homework Statement

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).

## 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?**
