This math topic focuses on comparing times taken by different moving entities based on their speeds and the distances they travel, with a complexity that involves unit conversions. Problems involve various moving subjects like bacteria, bugs, horses, and cars moving over specific distances at given speeds, all presented in different units of measurement (e.g., cm/hr, mm/d, m/s). The task is to determine which subject takes less time to complete their journey, enhancing skills in speed, distance, and time calculations along with unit conversions.
