What is the formula for calculating Velocity as per the Traffic Investigator's Reference Card?

The formula for calculating velocity, represented as V, is derived from the relationship between distance (D) and time (T). According to the formula, velocity is calculated by dividing the distance traveled by the time it takes to travel that distance. This is expressed mathematically as V = D/T.

This formula is fundamental in physics and traffic investigation as it allows investigators to ascertain how fast a vehicle is moving, which is crucial for understanding accident dynamics, assessing speed limits, and determining potential violations.

In contrast, the other options do not represent the correct relationship between distance and time for calculating velocity. For example, the second option incorrectly places time in the numerator, while the third option combines distance and time in an addition operation, which does not relate to velocity at all. The fourth option, which involves subtraction, also fails to capture the essence of how distance and time interact to produce velocity.
