Speed, Time, and 
Distance
Introduction to Speed, 
Time, and Distance
Speed (S) = Distance (D) / Time (T)
Time (T) = Distance (D) / Speed (S)
Distance (D) = Speed (S) * Time (T)
The relationship between speed, time, and 
distance is given by the formula:

Speed, Time, and 
Distance
Introduction to Speed, 
Time, and Distance
Speed (S) = Distance (D) / Time (T)
Time (T) = Distance (D) / Speed (S)
Distance (D) = Speed (S) * Time (T)
The relationship between speed, time, and 
distance is given by the formula:
Conversion Between 
Units
Converting Units:
To convert km/h to 
m/s, multiply by 
5/18.
To convert m/s to 
km/h, multiply by 
18/5.
Example:
Convert 15 km/h to 
m/s:
15 * 5/18 = 75/18 = 
25/6 m/s.

Speed and Time Relationship
Speed Increases
Time decreases for the 
same distance
Speed Decreases
Time increases for the 
same distance
Speed and Time are inversely proportional.
Example 1: If two people are travelling the same 
distance, one at x km/h and the other at y 
km/h, then the ratio of time taken by each to 
cover the same distance will be 1/y : 1/x.

Average Speed
1
Average Speed Formula:
Average speed = Total distance / Total 
time
2
This formula is used when a person is 
travelling different distances at different 
speeds.
Example 2: A man covers 60 km in 4 hours, what is his speed?
Speed = Distance / Time = 60 / 4 = 15 km/h
