Distance and Speed to Time - Changed Both Units (Level 2)

This math topic practices calculating the time needed for different objects to travel specified distances at given speeds. The problems cover a variety of units, including meters per second, millimeters per millisecond, centimeters per minute, and kilometers per second, with distances measured in corresponding units. Students must convert their answers into different time units such as minutes, seconds, or hours, demonstrating an understanding of both the basic speed formula and unit conversion. This is a more advanced exercise designed to strengthen skills in handling complex units and calculations related to speed, distance, and time.
