For Earth to rotate 60° will take four hours. Ish.
Earth takes 24 hours (approximately) to rotate a full 360°. 60° is 1/6 of this, so divide the full 24 hours by 6 to get 4 hours.
Rotate 360 degrees
1 hour
It goes right round 360 degrees in 24 hours, so 6 hours for 90 degrees, relative to the Sun. Relative to the distant stars, it takes the Earth about 5 hours, 59 minutes to rotate 90 degrees.
If the Earth rotates 15 degrees/hour, then 7.5 degrees is half of 15, so it takes half an hour or 30 minutes.
243 Earth days.

53 hours with 56 minutes
The Earth rotates one full rotation - 360 degrees - in 23 hours and 56 minutes.
A full rotation of Earth is considered one day if only the planet is observed, therefore the Earth will rotate 360 degrees in a day. If the rotation of the Earth is taken into account with the orbit around the sun, the Earth will rotate just under 361 degrees per day.
It would take a day (24 hours).
it takes 1 full month to rotate
It takes 23.9345 hours. The axis is tilted by 23.44 degrees.
