nasa has in the past used the gravity of other planets and the sun to fling their probes further into space.
The reason this works is the same reason planets stay in their orbit. Gravity pulls them in and basically it enters a state of freefall into the planet but due to its lateral motion it falls past the planet picking up speed.

It depends where you measure it. The speed of the space shuttle in orbit is around 17,850 mph. You do need to remember that the rocket is 'in orbit' only once it reaches it's maximum velocity. That's what makes it orbit. If it speeds up from there, the orbit just gets bigger. The Solid Rocket Boosters take the space shuttle to an altitude of 45 km (28 mi) and a speed of 4973 km per hour (3094 mph) before dropping off.

The one guys is basically right, push the pedal to the metal.
Increase the throttle or thrust to as much as you can. Once you are out of gravity a body in motion goes as fast in the opposite direction as the thrust of the engine.
You can ALSO use gravity to help you, by, for example, doing a sling shot from the moon. The moons gravity will draw you in and if you hit the right angle and then fire your rockets you can gain extra momentum from both pull and push.

If time is not an issue one option would be to go in the direction of a gravity field such as a planet or a star. Use the gravity field to accelerate your ship.

OR, emit a hydrogen molecule deflector beam in the path of your ship. This should decrease drag caused by friction that exist between the skin of the space craft and the hydrogen molecules in space. Less drag will result in increased speed and fuel economy.

Put the pedal to the medal! lol
OK, Ok, For every action there is a equal reaction. If a rocket has a rear thrust, it would be pushed forward from the reaction of that action.

since there is no air resistance in space, if you keep thrusting, your speed will keep increasing until the speed of the rocket equals the speed of the gass escaping from the thrust

If your rocket has mass m and is being propelled by a force F, then it is undergoing an accelleration a simce
a = F/m. Now, since velocity = acceleration * time,
all you have to do is wait.
If you want to go faster more quickly, increas F or decrease m

Velocity = distance/time
either you can manipulate time
or you can increase the amount of power propelling the rocket (ie-detonate a thruster by remote)

Sounds to me like a trick question. Maybe they don't use speed in space and instead use velocity. I hope this helps.
