Physics

To find the car's average velocity for the entire trip, we need to calculate the total displacement and the total time taken.

Calculate total displacement:

The car travels 300 km west and then 150 km east.

Displacement can be calculated as:

Total Displacement = 300km (west) - 150km (east) = 150km (west)

Calculate total time:

Time taken for the westward trip: 4 hours

Time taken for the eastward trip: 2 hours

Total Time = 4hours + 2hours = 6hours

Then, calculate average velocity:
