Which tools can be used to track the duration and distance of physical activity?

• A. Watches, activity trackers, pedometers, and accelerometers
• B. Only GPS devices
• C. Only stopwatch
• D. Only paper logs

Answer: (A)

Tracking how long you are active and how far you go relies on devices that record time and movement. Watches and activity trackers provide a clock and can time intervals, giving you clear duration data, and they often log activity automatically. Pedometers count steps and, with knowledge of your stride, estimate distance traveled. Accelerometers measure movement in multiple directions and, with processing, can estimate both the amount of movement and the distance covered. Using these tools together gives practical, objective measures of both duration and distance. Some devices also include GPS to directly measure distance and map routes, but the set of tools described covers the essential tracking of how long and how far you were active. A GPS-only option, a stopwatch alone, or paper logs either capture only distance, only duration, or rely on manual reporting, making them less comprehensive for this purpose.
