in one minute the earth spins 28km, so it spins 420km in 15 minutes
According to some scientists publications the average speed of the earth rotation is about 30km/s, so 15 minutes has to be 27000km
If the Earth rotates 15 degrees/hour, then 7.5 degrees is half of 15, so it takes half an hour or 30 minutes.
The Earth rotates 360 degrees in 24 hours, which means it rotates 15 degrees per hour (360 degrees / 24 hours = 15 degrees/hour). Therefore, in 2 hours, the Earth will rotate 30 degrees (15 degrees/hour x 2 hours = 30 degrees).
360 degrees is the intuitive answer, but it is not correct. The earth completes a 360 degree rotation in about 23 hours, 56 minutes and some odd seconds, which is the sidereal, or true, rotational period of the earth. I don't know the exact degrees in 24 hours, but it will be reasonably close to 361 degrees (roughly 1 extra degree per day to account for a full rotation over the course of a year).
It takes about 8-15 minutes for a rocket to reach space after launch, depending on the rocket's size and specific trajectory. Once in space, it can take several hours to travel far enough from Earth to be considered as "leaving" it.

Most satellites in low Earth orbit rotate around the Earth approximately 15 times per day. This means they orbit the Earth about every 90 minutes.
If the Earth rotates 15 degrees/hour, then 7.5 degrees is half of 15, so it takes half an hour or 30 minutes.
20 minutes. The Earth rotates 360 degrees every 24 hours. So it rotates 15 degrees every hour, so 5 degrees is 1/3 hours or 20 minutes.
The earth rotates 360o of longitude every 24 hours, so it takes 24 ÷ 360 hours to rotate 1o of longitude: 24 ÷ 360 hours = 24/360 hours = 1/15 hours = 1/15 x 60 minutes = 4 minutes The sun will cross 1o of longitude in the same time that the earth takes to rotate 1o of longitude, namely 4 minutes.
