This math topic focuses on calculating speed by converting distances and time into different units. Learners solve problems that involve changing both speed and distance from one set of units to another (e.g., kilometers per minute to meters per second, or centimeters per hour to meters per day). The problems provided range from scenarios involving rockets, bugs, and horses, each requiring unit conversions to determine the correct speed in a new unit such as meters per second, centimeters per day, or millimeters per minute. This advanced practice helps strengthen skills in unit conversion and rate calculations within the context of speed, distance, and time.
