## Homework Statement

An ambulance travels back and forth, at a constant speed, along a road of length

L. At a certain moment of time an accident occurs at a point uniformly distributed on the

road. (That is, its distance from one of the fixed ends of the road is uniformly distributed

over (0,L).) Assuming that the ambulance's location at the moment of the accident is also

uniformly distributed, compute, assuming independence, the distribution of its distance from

the accident.

## Homework Equations

## The Attempt at a Solution

Using X = ambulance position, Y = accident position I found

fx(x) = 1/L for x<= L

fy(y) = 1/L for y<=L

Now I'm stuck. :(
