That's aproximately the distance sound travels in one second, in air. Since light travels at a speed of 300,000 kilometers per second, the answer is, approximately 300,000 kilometers.
Its speed is the distance it travels per unit time.
The distance that a wave travels in a certain amount of time is a wavelength. Wrong,it's speed.(:
It will take less time.
A millionth of the distance that it travels in one second. Take the speed of light, in meters/second or kilometers/second, or even in miles/second, then divide that by a million to get the distance per microsecond.
Divide the distance by the time. Answer will be in meters/second in this case.
Because distance/time = the speed at which something travels.
That's aproximately the distance sound travels in one second, in air. Since light travels at a speed of 300,000 kilometers per second, the answer is, approximately 300,000 kilometers.
The average speed is one fifth of the distance that she travels from the third to the eighth second.
Its speed was 15cm per second. ( 75cm divided by 5 seconds = distance per each second, which is essentially an expression of speed).
If you are plotting distance versus time it is a straight line with slope 300000
Its speed is the distance it travels per unit time.
speed = distance/time = 100m / 50s = 2 m/s
Speed = Distance / Time
In a vacuum, electromagnetic radiation travels at a speed of 300,000,000 meters/second. Just convert the picoseconds to seconds, then multiply by the speed of light, to get the distance (in meters).
Distance = Rate * Timeso,Rate(speed) = Distance/Time= 112 meters/4 seconds= 28 meters/second
"Light-year" is not a speed, it is a distance - the distance light travels in a year.The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
