Which is Faster - Changed Distance Units (Level 3)

This math topic focuses on comparing speeds by solving problems related to "Which is Faster - Changed Distance Units," an advanced section under the broader unit of Speed, Distance, and Time. Each problem involves different entities such as bacteria, bugs, and horses moving over varied distances and time spans. Students must convert and compare these values (given in different units such as cm, m, mm, s, hr, and min) to determine which entity is faster. This requires understanding and applying concepts of unit conversion and rate comparison.
