Explanation:
The subject of this question is Martina's speed while riding her bicycle. Speed is calculated by dividing the total distance covered by the time it takes. In this case, Martina traveled 38.4 kilometers in 6 hours. So to find her speed in kilometers per hour, we should divide the total distance (38.4 km) by the total time (6 hours).
So, the calculation will be as follows:
