This math topic covers problems that deal with calculating time taken for a journey given a speed and distance, while also involving unit conversions. The focus is on various units of measurement such as centimeters per minute, millimeters per day, and meters per day, converting these into units of time like hours, minutes, and seconds. The problems typically involve small creatures like bugs and bacteria moving at specified speeds for set distances, requiring the learner to convert units and calculate the corresponding time for the journey.
