Mathematics

Speed, Distance and Time

Solve basic motion problems.

Speed = Distance / Time; Distance = Speed × Time; Time = Distance / Speed

Formula Explanation

These relationships apply when speed is expressed consistently with distance and time units.

Variables Explained

Distance = total path length; Time = elapsed time; Speed = distance travelled per unit time.

Solved Example

A vehicle travels 150 km in 3 hours. Find its average speed.
Speed = 150 / 3 = 50 km/h.

Exam Tip

Convert units before calculation, especially km/h and m/s.
