This math topic focuses on calculating time taken given speed and distance. It explores the use of consistent units like meters per second (m/s), meters per minute (m/min), millimeters per hour (mm/hr), kilometers per hour (km/hr), centimeters per hour (cm/hr), and meters per day (m/d) to determine the duration required for various modes of transport (cars, horses, bacteria, bugs) to cover specific distances. Skill in isolating the variable time from the speed-distance relation is central here. Each problem is structured as a multiple-choice question, presenting different scenarios to apply the basic formula: time = distance / speed.
