A car travels 150 km for two hours east of a starting point, turns around and travels due west 300 km for three hours. What is the car's net velocity for the trip?

To calculate the car's net velocity for the trip, we need to determine the total displacement and the total time taken.

1. The car travels 150 km for two hours east of the starting point. This means the displacement in the east direction is 150 km.
2. The car then turns around and travels due west for 300 km for three hours. The displacement in the west direction is -300 km (negative since it's in the opposite direction).
3. To find the total displacement, we need to sum up the displacements in the east and west directions: 150 km + (-300 km) = -150 km.
4. The total time taken is the sum of the two hours going east and the three hours going west: 2 hours + 3 hours = 5 hours.
5. To calculate the net velocity, divide the total displacement by the total time taken: -150 km / 5 hours = -30 km/h.

Therefore, the car's net velocity for the trip is -30 km/h, indicating that it was moving at a speed of 30 km/h to the west.

To find the car's net velocity for the trip, we need to calculate the total displacement divided by the total time taken.

First, let's determine the total displacement.

When the car travels 150 km for two hours east of the starting point, the displacement is +150 km (east direction).

Then, when the car turns around and travels due west 300 km for three hours, the displacement is -300 km (west direction).

To find the total displacement, we add these two displacements:

Total displacement = +150 km - 300 km = -150 km

Next, we need to calculate the total time taken.

The car traveled for 2 hours in one direction and then 3 hours in the other direction. So, the total time taken is 2 hours + 3 hours = 5 hours.

Finally, we can calculate the net velocity by dividing the total displacement by the total time taken:

Net velocity = Total displacement / Total time taken
= -150 km / 5 hours
= -30 km/h

Therefore, the car's net velocity for the trip is -30 km/h, indicating that it was moving at an average speed of 30 km/h in the west direction.
