What is the formula used to calculate speed?

• A. Distance = speed × time
• B. Speed = distance / time
• C. Time = distance / speed
• D. Velocity = distance / time

Answer: (B)

Speed is how fast something moves, measured as distance covered per unit of time. The formula used to calculate speed is distance divided by time. For example, traveling 200 meters in 10 seconds gives a speed of 20 meters per second. The other equations relate to other quantities: distance equals speed times time, which you use to find distance when you know speed and time; time equals distance divided by speed, which solves for time; and velocity equals distance divided by time, which is the same rate as speed but with a direction. Since the question asks for the formula for speed, the division of distance by time is the defining relationship.
