Answer:
B) 24 km/h south
Explanation:
The average velocity of the motorcycle is given by:
[tex]v=\frac{\Delta p}{\Delta t}[/tex]
where
[tex]\Delta p[/tex] is the displacement (variation in position)
[tex]\Delta t[/tex] is the time interval
From the graph, we observe that:
[tex]\Delta p = 150 km - 30 km = 120 km[/tex]
[tex]\Delta t = 5 h - 0 h=5 h[/tex]
So, the average velocity is
[tex]v=\frac{120 km}{5 h}=24 km/h[/tex]
And the direction is south, since the motorcycle is moving south.
