Speed - Which is Further - Changed Both Units (Level 3)

This math topic focuses on comparing distances by using the concepts of speed, distance, and time, with varied units. Each problem provides two scenarios where different entities (like planes, bugs, horses, and bacteria) move at given speeds for specified durations. The units of speed and time are intentionally varied (e.g., meters per second vs. kilometers per hour, or seconds vs. minutes) to challenge the learner to convert these units for accurate comparison. The primary skill practiced is converting and comparing distances calculated from given rates and times in different units.
