This topic focuses on calculating speed using the formula speed = distance/time. Students address problems where they need to determine the average speed of a car that travels a specific distance over a given period of time expressed in clock hours. Problematization occurs through various examples and requires conversion of time from hours and minutes to just hours to compute speeds in kilometers per hour (km/hr). The questions are structured in multiple-choice format, providing various options for the calculated speeds. This helps reinforce the application of concepts related to speed, time, and distance in practical scenarios.
