Which equation represents the relationship between speed, distance, and time?

The relationship between speed, distance, and time is captured by the equation that states speed is equal to distance divided by time. This is due to the definition of speed, which quantifies how much distance is covered in a certain amount of time.

In practical terms, if you travel a distance of, say, 100 meters in 5 seconds, to find the speed, you would divide the distance (100 meters) by the time taken (5 seconds), resulting in a speed of 20 meters per second. This illustrates how speed measures the rate of movement over a period and establishes a clear mathematical relationship between these three variables.

In contrast, other choices incorrectly combine distance and time using addition, subtraction, or multiplication, which do not accurately represent the physical relationship between these quantities. The only correct mathematical expression that accurately conveys how speed relates to distance and time is the division.
