Understanding Average Speed

Average speed is a fundamental concept in physics and mathematics that measures the distance traveled by an object over a given period of time. It is an essential parameter in various fields, including transportation, engineering, and economics. In this article, we will explore the concept of average speed using a real-world example: a train traveling from an unknown location to Chicago.

The Problem

A train traveled 800 kilometers to Chicago in 8 hours. What is the train's average speed?

Calculating Average Speed

To calculate the average speed of the train, we need to use the formula:

Average Speed = Total Distance / Total Time

In this case, the total distance traveled by the train is 800 kilometers, and the total time taken is 8 hours.

Step 1: Identify the Given Values

• Total Distance = 800 kilometers
• Total Time = 8 hours

Step 2: Apply the Formula

Average Speed = Total Distance / Total Time = 800 km / 8 hours = 100 km/h

Conclusion

Therefore, the train's average speed is 100 km/h.
