This math topic focuses on calculating and comparing travel times when different speeds and distances are involved. Each problem requires converting varied units of speed (e.g., km/min, m/s, cm/ms) to determine which of two options results in a shorter travel time. This set of exercises is advanced, incorporating both speed conversions and time calculations as part of broader lessons on speed, distance, and time.
