Walking speed is defined as the product of which two factors?

• A. Walking speed = Step width × base of support
• B. Walking speed = Hip ROM × ankle ROM
• C. Walking speed = Step length × cadence
• D. Oxygen consumption and gait speed

Answer: (C)

Walking speed is the rate at which forward distance is covered, and it comes from two factors: how far you move with each step (step length) and how many steps you take per unit time (cadence). Multiply step length by cadence to get distance per unit time, which is speed. For example, a step length of 0.75 m taken at 90 steps per minute gives 0.75 × 90 = 67.5 m/min (about 1.1 m/s). The other options relate to stability, joint motion, or energy use, not the direct geometric definition of speed.
