Answer:

5.0 km west

Step-by-step explanation:

Velocity is the ratio between displacement and time taken for the motion:


v=(d)/(t)

where d is the displacement and t the time taken.

In this problem, we know:

- velocity:
v= 15.0 km/h

- time taken:
t=20 min=(1)/(3)h

So, we can re-arrange the formula to calculate the displacement:


d=vt=(15.0 km/h)((1)/(3)h)=5.0 km

and the displacement has the same direction of the velocity (to the west)
