Speed - Which is Faster - Changed Time Units (Level 2)

This math topic involves comparing speeds of different objects when the time units are varied. The skills practiced involve calculating and understanding speed in non-standard units such as meters per minute, kilometers per day, and millimeters per millisecond. The exercises often require converting between different time units to assess which of two entities (e.g., bugs, horses, or spaceships) is moving faster given its distance covered within a specified time frame. This topic is part of an advanced unit on Speed, Distance, and Time.
