Final answer:
The equation representing the relationship between distance traveled (D) and the number of hours (T) for the flight from New York to London is D = 500T. This equation shows that as the number of hours increases, the distance traveled also increases.
Step-by-step explanation:
The equation representing the relationship between distance traveled (D) and the number of hours (T) for the flight from New York to London is D = 500T, option (a).
This equation shows that the distance traveled is directly proportional to the number of hours. As the number of hours increases, the distance traveled also increases.
For example, if the flight is 2 hours long, the distance traveled would be 2 * 500 = 1000 miles. If the flight is 5 hours long, the distance traveled would be 5 * 500 = 2500 miles.
