Which is Less Time - Changed Time Units (Level 1)

This math topic focuses on comparing travel times of different entities that move at specified speeds over certain distances. It involves calculations where some of the time units may need to be converted (such as from hours to minutes, or days to hours) to accurately determine which entity takes less time to complete its journey. The problems use various units of measurement for distances (like mm, cm, m, km) and speeds (mm/hr, mm/s, cm/min, km/hr, etc.), requiring the application of concepts from the broader unit of Speed, Distance, and Time at an advanced level.
