Try an example:

How the Speed, Distance & Time works

  1. Use speed = distance ÷ time (and rearrange for the unknown).
  2. Keep units consistent: convert minutes to hours or km/h to m/s first.
  3. For two moving objects, add speeds when approaching and subtract when chasing.

Frequently asked questions

How do I find average speed?

Total distance divided by total time, not the average of the speeds.
