WebIf the starting time t0 is taken to be zero, then the average velocity is simply. \displaystyle \bar {v}=\frac {\Delta x} {t} v¯ = tΔx. Notice that this definition indicates that velocity is a vector because displacement is a vector. It has both magnitude and direction. WebThe basic equation for solving this is: d = vt + (1/2)at 2 where d is distance traveled in a certain amount of time (t), v is starting velocity, a is acceleration (must be constant), and t is time. This gives you the distance traveled during a certain amount of time. If you know any 3 of those things, you can plug them in to solve for the 4th.
