Overview

Speed, distance, and time are closely connected ideas used to describe motion. Speed tells how much distance is covered in a given time. Distance tells how far an object travels. Time tells how long the journey takes. These three quantities are linked by simple formulas and unit conversions, and the

Key Concepts

Speed is the distance covered by

Speed is the distance covered by a moving object in unit time. The formula is Speed = Distance / Time. In metres and seconds, speed is in m/s. In kilo

Distance is the quantity covered by

Distance is the quantity covered by a moving body. It is found by Distance = Speed × Time.

Time is the duration taken

Time is the duration taken to cover a distance. It is found by Time = Distance / Speed.

1 km/h equals 5/18 m/s

1 km/h equals 5/18 m/s, and 1 m/s equals 18/5 km/h or 3.6 km/h. To convert km/h to m/s, multiply by 5/18. To convert m/s to km/h, multiply by 18/5.

Average speed is obtained by dividing

Average speed is obtained by dividing the total distance covered by the total time taken. It is used when speed changes during a journey.

Learning Objectives
