How do we compute average speed?
To compute average speed, you need to divide the total distance traveled by the time it took to travel that distance
To compute average speed, you need to divide the total distance traveled by the time it took to travel that distance. The formula for average speed (S) is:
S = total distance / total time
Here is a step-by-step explanation of how to calculate average speed:
1. Determine the total distance traveled. This can be measured in various units such as kilometers, miles, or meters. For example, let’s say the total distance traveled is 200 kilometers.
2. Determine the total time taken to travel that distance. This should be measured in the same unit as the distance, and can be in seconds, minutes, hours, or any other consistent time unit. For instance, let’s say the total time taken is 4 hours.
3. Divide the total distance by the total time to obtain the average speed. Using the given values from the previous steps:
S = 200 km / 4 hours
4. Simplify the expression:
S = 50 km/h
So, the average speed in this example is 50 kilometers per hour.
Note: It is important to keep the units consistent throughout the calculation. If the distance is in miles, the time should be in hours, and if the distance is in meters, the time should be in seconds.
