This math topic focuses on problems related to converting and calculating speed when the units of distance and time are changed. Problems involve determining the speeds of various moving objects like bugs, horses, cars, and bacteria when given their distances in meters, centimeters, or millimeters and times in days, minutes, seconds, milliseconds, or hours. The questions require converting these units appropriately to compute the speed in different units such as mm/d, mm/min, mm/s, cm/s, m/ms, and m/hr, reflecting an advanced understanding of speed, distance, and time calculations.
