What is the formula to calculate Average Travel Speed?

The formula to calculate Average Travel Speed is determined by dividing the total distance traveled by the total time taken for that travel. This relationship arises from the basic definition of speed in physics, where speed is the measure of how quickly an object moves through space.

When you divide Travel Distance by Total Travel Time, you obtain the average speed as a rate. Essentially, this formula tells you how many units of distance are covered per unit of time, providing a clear understanding of the rate of movement. For example, if you travel 100 miles in 2 hours, the average travel speed calculated with this formula would be 50 miles per hour.

In contrast, the other formulas presented do not yield the correct calculation for average speed. Multiplying travel distance by travel time would give a result that misrepresents the concept of speed since it combines both measures in a way that does not reflect the rate of travel. Dividing total travel time by travel distance would provide a measurement of time per unit of distance, which is the reciprocal of speed but not a measure of speed itself. Lastly, subtracting total travel time from travel distance does not relate to speed at all and results in units that do not correspond to a speed measurement.

Thus, the correct approach to
