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

This math topic explores problems related to calculating the time taken by different creatures (bugs and bacteria) to travel specified distances at given speeds. The scenarios require conversion between different units of speed and distance (such as cm/min, m/s, mm/hr, and cm/d) to determine which creature completes its journey in less time. This set of problems is advanced and part of a broader unit on Speed, Distance, and Time, designed to challenge understanding and application of these concepts in varying contexts.
