Distance Time Graphs GCSE Physics. Calculating speed using distance time graphs. Change in time 4 - 0 4 s speed fracdistancetime.
D v x t where v is the velocity average speed t is the time and d is distance so you can read it as Distance Speed x Time.
Assess what information you are given. For the speed you need to enter its value and select speed unit by using the scroll down menu in the calculator. Velocity is speed in a given direction. Movement can be shown in distance-time and velocity-time.
