Final answer:
The velocity of the plane that traveled from Cairo to Luxor is 200 km/h.
Step-by-step explanation:
The velocity of a plane that traveled 1000km from Cairo to Luxor in 5 hours can be calculated by dividing the total distance traveled by the time taken. In this case, the velocity is 200 km/h.
Velocity is a vector quantity that includes both magnitude (speed) and direction. In this case, the direction is from Cairo to Luxor.
To calculate the velocity more precisely, you would need to consider factors such as changes in speed or direction during the journey. However, based on the information provided, the average velocity is 200 km/h.
