This math topic involves calculating speed given distance and time, with all quantities in the same units. Students are required to use the formula for speed, which is distance divided by time, to determine the rate of travel of various moving objects such as bacteria, cars, bugs, and horses. Problems range from linear measurements in millimeters, meters, and kilometers combined with time units from seconds to days. Each question presents a practical scenario and asks for the speed, providing multiple-choice answers to enhance problem-solving skills in the context of speed calculations.
