This is the full question to the question i recently posted.i really dont understand it?

If you were riding in a spaceship traveling at 160 kilometers per hour (100 mph), about how long does it take to get to the Moon, Mars, Saturn, Pluto, the star closest to the Sun, and the center of our galaxy? How long will it take if you could somehow travel at the speed of light 300 thousand kilometers per second (186,000 miles per second)? Write your new estimates of how long it would take to get to each of these five places traveling at 160 kph, 100 mph, and 300,000 kps in the space below and compare your initial answers to your new answers.
