Which is Further - Changed Time Units (Level 3)

This math topic focuses on problems that require calculating and comparing distances traveled by two moving objects with different speeds and time durations, including conversions between different units of time. The exercises provide a deeper understanding of relationships between speed, distance, and time within varied contexts like moving rockets, trotting horses, crawling bugs, and bacteria movements. Each scenario necessitates converting units of time (e.g., seconds to minutes, days to hours) to determine which object travels further, enhancing skills in unit conversion and application of the distance formula.
