Speed - Speed and Time to Distance - Changed Distance Units (Level 3)

This topic focuses on advanced problems related to calculating distances using given speeds and times, while incorporating unit conversions. The exercises simulate scenarios involving different creatures and vehicles, such as horses, bugs, spaceships, bacteria, and cars, moving at specified speeds over certain durations. The primary challenge involves converting units of speed (like cm/s, mm/min, m/ms, cm/d, and m/s) to distance units (meters, kilometers, or millimeters), requiring multiplicative adjustments and attention to dimensional analysis. This set of problems helps strengthen skills in applying formulas and understanding unit conversions within a speed, distance, and time context.
