To calculate speed, you generally use the following formula:
Speed
=
Distance
Time
Speed=
Time
Distance
Where:
Speed is the rate at which an object moves.
Distance is how far the object travels.
Time is how long it takes the object to travel that distance.
Examples:
If you travel 100 meters in 20 seconds, the speed would be:
Speed
=
100
meters
20
seconds
=
5
m/s
Speed=
20seconds
100meters
=5m/s
If a car travels 150 kilometers in 3 hours, the speed would be:
Speed
=
150
km
3
hours
=
50
km/h
Speed=
3hours
150km
=50km/h
