This topic focuses on converting and calculating speeds using given distances and times, while changing the units for speed. It covers conversions among different measurement units, such as millimeters to centimeters and hours to days or seconds. The problems involve organisms like bacteria and bugs moving over certain distances and the calculations determine their speeds in varied units like cm/day, cm/second, mm/minute, km/day, mm/hour, cm/hour, and km/minute. This advanced practice develops skills in unit conversion and formula application for speed (distance/time) calculations.
