This math topic focuses on calculating which of two scenarios requires less time, given different speeds and distances. The worksheet consists of problems that require conversion between units of speed and distance, such as mm/min to cm/d, cm/ms to m/s, and m/hr to mm/s. Students are tasked to determine which of the two entities, like bacteria, cars, bugs, or horses, traverses their assigned distance in less time by applying their understanding of speed, distance, and time calculations alongside unit conversions. This is an advanced exercise in dealing with complex unit changes and time calculations.
