    The answer is the third option, " about 18,000 miles per hour ". If you just want to get a spaceship into orbit around the Earth, the spaceship will need to reach a minimum speeds of about 4.9 miles per second, which is equivalent to 17,600 miles per hour (about 18,000 miles per hour to the nearest thousand).
