A space probe is 7.62 x 10 to the 7th power kilometers from the surface of the planet Mars. If the space probe is traveling towards mars at a arate of 127 meters per second, how many hours will it take the probe to reach the surface of the plant? Round to the nearest hour.

Help!? I don't understand what to do to understand how many hours!
