The speed of light is 186,282 miles per second, or 670,616,629 miles per hour.
The speed of sound is commonly quoted as 761 miles per hour. However, this is only correct for in air that's at 21 degrees Celsius. As the temperature of the air increases, so does the speed of sound.
In water, the speed of sound is much higher - 3,315 miles per hour.

light speed = 186,000 mi/sec, not mph as stated in the answer above
sound = approx 1100 fps = ~ 750 mph, but is a function of pressure
