Unit Conversion and Measurement Problems

This video tutorial explains how to convert speeds from miles per hour (mph) to meters per second (m/s) and vice versa. It covers the necessary conversion factors, including miles to kilometers, kilometers to meters, and time conversions from hours to seconds. The video provides a step-by-step guide on performing these conversions, including a practical example of converting 45 mph to m/s and then reversing the process for 15 m/s to mph.
