This math topic involves converting and calculating speeds given various units of distance and time. The skills practiced include computing the speed from distance and duration details, followed by converting the resultant speed into different units. Problems involve conversions between meters, centimeters, millimeters, hours, minutes, seconds, and days. Each question provides an initial speed in one set of units and asks for the conversion to another, testing the students' abilities to handle both calculation and unit conversion in the context of speed.
