Which is Less Time - Same Units (Level 1)

This math topic focuses on understanding the relationship between speed, distance, and time. Specifically, it presents scenarios involving different creatures and objects (like bacteria, bugs, and horses) moving at specific speeds and covering particular distances. The task is to determine which subject takes less time to complete their journey, assuming all in the same unit of measurement. This is aimed at improving basic calculations and intuition regarding the fundamental concepts of speed, distance, and time.
