The automobile beltway around many cities is approximately circular. Suppose that you start driving at point A on the east side

of the beltway and drive counterclockwise at an unchanging 90 km/hr (Figure 3.13). As you pass point B on the north side, what is your speed? Your velocity?

speed is the magnitude of velocity which is given as 90 km/hr and it does not change. only the direction change , the direction at any time is given by the tangent to the circle at that time and location.

from the diagram , at north side, the velocity is directed in west direction

Your speed at point-B is 90 km/hr.

Your velocity at that point is 90 km/hr to the west.
