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.
