Answer:
D. 90km/hr due West
Explanation:
Given parameters:
Displacement = 1215km
Time = 13.5hr
Unknown:
Velocity = ?
Solution:
Velocity is the displacement divided by the time taken;
Velocity = [tex]\frac{displacement}{time}[/tex] = [tex]\frac{1215km}{13.5hr}[/tex] = 90km/hr
Velocity is 90km/hr due West
