This math topic focuses on calculating speed when distance units are changed, primarily using small units of measurement like millimeters (mm), centimeters (cm), and meters (m). The problems involve converting times such as seconds, hours, days, and minutes into different time units and then calculating the speed. Examples include determining the speed of a bug crawling a specific distance in a given time, a bacteria moving, and hypothetical situations like a car driving a short distance in milliseconds. Various options for the answer highlight the need for precise conversion and calculation of speed.
