Physics

To calculate the average velocity of the plane for the entire journey, we need to determine the total displacement and the total time taken.

Calculate total displacement:

The plane travels 300 km south and then 660 km north.

Total Displacement = 660km (north) - 300km (south) = 360km (north)

Calculate total time:

Time taken for the southward trip: 1 hour

Time taken for the northward trip: 2 hours

Total Time = 1hour + 2hours = 3hours

Then, calculate average velocity:
