Which is Less Time - Changed Time Units (Level 3)

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.
