Question #3cc11

Answer 1

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.
