Final Answer :
B
Explanation :
The formula expresses the relationship between the variables distance, speed, and time. It states that time is directly proportional to distance and inversely proportional to speed, which means that as distance increases, time increases proportionally, while as speed increases, time decreases proportionally. This is why option B is the best choice because it uses the correct terminology of direct and inverse variation to describe the relationship between these variables.
