90 mi
125 kmh or 78.125 mph
Just divide the distance by the speed.
Frequency
The speed at which a wave passes through water or other medium is called phase velocity.
The Speed At Which Wave Travels Is Known As Wave Velocity.It Is Denoted As 'v' which Equals The Product Of Its Frequency And Wavelength.
Electromagnetic wave, namely, light as it travels through denser medium its speed decreases from its speed when it travels through air or vacuum.
The medium in which it travels through
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
Sound is affected by the media. It travels high speed in solids generally.
density
amplitude
Over 6,000 mph.
floating
Sound travels at different speeds depending on the medium. Sound will travel the fastest through solids.
