This math topic focuses on calculating speed from given distances and times while also converting between different units of measurement. It addresses problems where students are required to compute the speed of various moving objects such as horses, rockets, bugs, and planes, given their travel distance and time. The scenarios necessitate conversion of units for distance (e.g., meters to centimeters, kilometers to meters) and time (e.g., minutes to seconds), demanding proficiency in both speed calculation and unit conversion. Each question offers multiple-choice answers, fostering the ability to solve and validate through selection.
