As speed of light >> speed of sound, we can safely assume that the time taken for light to reach the observer is negligeable. Taking speed of sound to be 340 ms-1 The distance can be found out by the formula Distance = Speed * Time = 340 * 3.4 = 1156 m
If you mean points of (1, -2) and (-9, 3) then the distance is about 11 units using the distance formula
using the formula, speed squared divided by 20 plus speed gives 40 feet approximate stopping distance at 20mph.
Formula: C
If you mean points of (-5, 1) and (-2, 3) then using the distance formula it is the square root of 13 or about 3.6
If you mean points of (-5, 1) and (-2, 3) then using the distance formula it is the square root of 13 or about 3.61 rounded to 2 decimal places
The distance to the horizon, d kilometres, is related to the height above mean sea level, h metres, by the approximate formula: d = 3.57*sqrt(h).
Pythagoras invented the distance formula
If the formula was correct for calculating the distance of a flash of lightning by counting the seconds from the flash to hearing the sound of the thunder, the distance would be ten miles (one second = one mile).However, the actual formula is: seconds divided by five equals distance of the lightning in miles. So a ten second delay means the lightning was about two miles away.This is because the light reaches you almost instantaneously (at the speed of light in air actually!), but sound travels at 343.14 meters per second (1,125.79 ft/s). This is 1,235.30 kilometers per hour (767.58 mph), which is about one mile in five seconds.For more information, See Related links below this box
Use the formula: distance = time x speed.Use the formula: distance = time x speed.Use the formula: distance = time x speed.Use the formula: distance = time x speed.
== I'm pretty sure the formula for distance is: D== rt (Distance= rate x time) == The formula for distance is: speed x time.
It is the same as the distance formula. DISTANCE FORMULA: d=square root of (x2-x1)^2+(y2-y1)^2
