Speed - Distance and Time to Speed - Changed Time Units (Level 3)

This math topic focuses on converting measurements of speed, with problems involving different time units to express the speed of various moving objects like bugs, bacteria, and a car. It emphasizes calculations of speed from given distances and time spans, subsequently converting these speeds into different units such as meters per day, millimeters per hour, centimeters per hour, and millimeters per second. These problems help in understanding and practicing speed conversions and unit changes within the broader context of speed, distance, and time. Multiple-choice answers are offered for each question to test understanding.
