What is the formula for calculating speed?

The formula for calculating speed is expressed as distance divided by time, which can be simply written as d/t. This means that if you know the total distance traveled and the time it took to travel that distance, you can determine the speed.

For example, if a car travels 100 kilometers in 2 hours, you would divide 100 by 2 to find that its speed is 50 kilometers per hour. This formula captures the basic relationship between distance, speed, and time, laying the foundation for understanding motion in physics.

While other options introduce additional components or variables related to physics, they either expand upon or complicate the basic formula for speed. The correct choice succinctly provides the straightforward calculation needed to find speed.
