Which is Faster - Changed Time Units (Level 1)

This topic focuses on comparing speeds by examining situations where two entities (such as bugs, cars, bacteria, or horses) cover different distances over different times, with the challenge of time units being different for the two entities compared. Students must determine which of the two is faster. This requires converting time units to a common unit for a fair comparison and then calculating speed by dividing distance by time to ascertain which entity moves faster. These problems are a part of an advanced study on speed, distance, and time.
