V d t where v is the velocity d is the distance and t is the time so you can read it as Speed Distance Time. Indeed light is one form of electromagnetic radiation as are. To solve for speed or rate use the formula for speed s dt which means speed equals distance divided by time.
At 20 C 68 F the speed of sound in air is about 343 metres per second 1235 kmh.
It can also be expressed as the time derivative of the distance traveled. Mathematically it can be written as v st or v dsdt where speed is denoted by v distance is denoted by s and time is denoted by t. S 270 kmh. Velocity is a vector value meaning that velocity includes direction.
