Which is Faster - Changed Both Units (Level 1)

This topic focuses on comparing speeds in different units, specifically altering both distance and time units. Students are challenged to determine which of two moving entities (like bacteria or bugs) is faster based on given distances traveled over specific time spans. The problems require students to convert units of measurement for accurate comparisons, enhancing their understanding of speed within the context of distance and time. This is part of an advanced study on speed, distance, and time concepts.
