Final answer:
The question does not provide enough information to determine the correct speed for a light plane to reach.
Step-by-step explanation:
To determine the speed required for a light plane to travel, we need to consider the information provided in the question. Unfortunately, the question itself does not directly provide any information about the speed the plane needs to reach. Therefore, I cannot determine the correct answer based on the given options.
However, in physics, the speed of a plane can depend on various factors such as the type of plane, its engine power, the wind speed and direction, and the desired destination.
These factors can affect the required takeoff and cruising speeds of the plane. It is important to note that different planes have different speed capabilities, and the specifics of the plane in question are not provided.
If you have additional information or a specific context for this question, please provide those details so that I can assist you further.
