(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An electron moves in the positive x-direction a distance of 2.44 m in 3.10 *10-8 s, bounces off a moving proton, and then moves in the opposite direction a distance of 1.68 m in 3.53*10-8 s.

3. The attempt at a solution

to find the average velocity I used the distance formula to find magnitude divide it by the c

Sqrt (2.44)^2+(1.68)^2 / (3.53*10^8 - 3.10*10^8) ?

for the average speed

(2.44 - 1.68) / (3.53*10^8 - 3.10*10^8)?

Can someone explain it by showing some work? I keep getting the wrong answer.
