## Homework Statement

A car averages 80 km/h travelling from A to B, and then on the return trip the car averages 60 km/h from B to A. Write the average speed of the car, V, as a function of x, where x is the distance from A to B.

## Homework Equations

Not sure what to use.

## The Attempt at a Solution

Vavg = [80 km/h(x) + 60 km(x)]/2

Obviously it's wrong =/
