centi- is a SI prefix meaning 1/100. It comes from a Latin word meaning "hundred."
So, 1 meter = 100 centimeters
If you have 10 meters, multiply both sides by 10:
1 meter * 10 = 100 centimeters * 10
10 meters = 1000 centimeters

However, you asked on an automotive forum, so asking "how long would it take to go ...?" sounds like you are asking for an amount of time that it takes to travel a certain distance. But, since you do not state the rate of speed (mph, kph, fps, etc.), we cannot answer that question, other than giving you some guesses based on some given speeds.
