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

This math topic focuses on comparing time durations taken by different moving objects when experienced speed and distance are given in various units. Specifically, it practices solving problems related to "Which takes less time?" where students must compare how long two bugs, bacteria, or planes take to travel specified distances at given speeds. Speed units vary among problems and are presented in meters per hour, centimeters per minute, millimeters per second, and kilometers per minute, requiring students to convert units to determine which object travels faster over the given distance.
