20 m
Relative or apparent motion.
wave speed
Speed of the wave.
If a body travels at a constant speed it will travel a certain distance (doesn't matter how far for our purposes). If it's accelerating then its speed is constantly increasing and therefore it covers more distance over every increment of time that it would if it were moving at its initial speed. So, acceleration increases displacement.

60km. 80*.75 = 60.00
The speed of a wave is how far the wave travels in one unit of time.
It depends opon the speed of the bike.
one and a half times 20, ie 30 miles
Relative or apparent motion.

wave speed
Speed of the wave.
It's a bad question because 5 meters per second per secondis not"a constant speed"it is a rate of acceleration.5 x 5 = 25 meters traveled.
In general, light propagates at c, the speed of light (that is, 299,792,458m/s), however when travelling through a medium such as an optical fibre, this will decrease, but will still travel at a constant speed dependent upon values such as the materials permittivity and permeability. Light travels easiest through insulating mediums, and cannot travel far through conductors.
the object's "speed".(not 'velocity')
