Question #3cc11

1 Answer

24000km, or 120^@, or (2pi)/3 radians

Explanation:

It travels 72 000 km in 24 hr.
8 hr is 1/3 of 24 hrs
It travels 1/3 of 72 000 km
72000/3=24000 km
But the question asks for the angular displacement, which is the displacement around the circle as an angle.
In this case it is 1/3 of the circle, so 120^@, or (2pi)/3 radians.
