Which is Faster - Changed Both Units (Level 3)

This math topic focuses on comparing speeds, involving complex unit conversions in both distance and time dimensions. The questions challenge students to determine which of two entities is moving faster by comparing speeds that are given in different units. Example problems include converting units like meters to kilometers and seconds to minutes or hours, and then computing the speed to see which entity is faster. The content is part of an advanced "Speed, Distance, and Time" unit, requiring a good understanding of unit conversion and basic calculation of speed.
