Answer:
v = 78.5 km/h
Explanation:
It is given that, the distance between one city to another is 314 km. The overall trip takes 4 hours. We need ton find average velocity. It is equal to the total displacement divided by total time taken. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{314\ km}{4\ h}\\\\v=78.5\ km/h[/tex]
So, average velocity is 78.5 km/h.
