This math topic focuses on calculating speed by converting distances and times across different units. It helps develop skills in converting and computing speeds in various units such as millimeters per millisecond, meters per minute, centimeters per second, kilometers per second, meters per hour, and millimeters per second. Each problem provides a scenario involving a distance traveled and the time taken, asking for the speed in a specific unit, enhancing understanding of both unit conversion and speed calculation.
