Acar travels 200.0 miles west for two hours. then it travels another 75.0 miles west for an additional hour. what is the average velocity of the entire trip?

91.7 mph west

Explanation:

The average velocity is the ratio between the displacement and the time taken:

where d is the displacement and t the time taken.

First of all, we need to find the net displacement. We know that the car moves

200.0 miles west + 75.0 miles west = 275.0 miles west

While the total time taken is

So now substituting into the equation above, we find the average velocity:

And the direction is the same as the displacement, so west.
