Average Velocity Calculation of a Train Journey

What is the average velocity of a train that traveled 400 miles north and 275 miles south in a total trip of 5 hours?

Calculate the average velocity in mph.

Answer:

The average velocity of the train is 25 mph north.

Explanation of Average Velocity Calculation:

When determining the average velocity of a train, we need to consider the total displacement covered and the total time taken for the journey.

The train traveled 400 miles north and 275 miles south, resulting in a net displacement of 125 miles north (400 miles - 275 miles).

To calculate the average velocity, we use the formula: Average velocity = displacement / time. In this case, the displacement is 125 miles north and the total time taken is 5 hours.

Substitute the values into the formula: Average velocity = 125 miles / 5 hours = 25 mph north.
