Question: 1 / 400

How is average speed mathematically expressed?

Time divided by distance

Speed equals time over distance

Speed equals distance over time

Average speed is mathematically expressed as the total distance traveled divided by the total time taken to travel that distance. This relationship can be framed as "Speed equals distance over time," which highlights that to find speed, you must know how far an object has traveled and how long it took to travel that distance.

In practical terms, if a vehicle covers a distance of 100 kilometers in 2 hours, the average speed would be calculated as follows: speed = distance (100 km) / time (2 hours) = 50 km/h. This formula is fundamental in understanding motion in physics and daily activities, emphasizing that average speed provides a measure of how quickly an object moves in relation to the distance covered over a specific duration.

The other options presented do not rightly represent the relationship between speed, distance, and time, leading to misunderstandings of fundamental concepts in motion.
