I think it must be 300 x 30...
Light travels at 186000 miles per second in vacuum.
300 feet per second = 204.54 mph
Nothing can travel faster than the speed of light which is 1080 million kms per hour. ( 300 x 106 metres per second)
Multiply by 10e9 Gm = 1 000 000 000 m Gm/s x 1 000 000 000m/s = 1.0 x 109m/s
Sound travels, in air, at about 320 meters per second. Light travels about 300 000 000 meters per second
300,000 km per second is the approximate speed of light.
sound travels over 300 meters per second. do the math ;) but light is just about 300 000 kilometers per second!
Light travels at 300 000 km/second Multiply that by 3600(the number of seconds in an hour) 300 000 x 3 600 = 1 080 000 000 or 1.08 billion miles per hour.
light travels 3x10 to the power of 6, which equals out to be 300, 000 0 miles per sec
3*108 miles per second.
In a vacuum, light always travels at the same speed, about 300 000 kilometers per second.
Light travels at the speed of 186,000 ft per second in a vacuum.
Infrared rays travel at the speed of light, which is approximately 299,792 kilometers per second in a vacuum.
Please note that the speed is the same for 1 second or for 1 hour or whatever. Light travels 300,000 km per second, or 300 million meters per second.

First of all, let's get our constants straight. "Miles" is not a speed, and thespeed of sound is not 330 miles per anything. 330 meters per second is areasonable value to use for the speed of sound.1,500/330 = 4.545 seconds.(rounded)
