Wave Speed = Distance travelled ( No.of seats ) / Time (in seconds)
Wave Speed ,V= (868 seats)/(31.2 s) = 27.8
seats/second
Width of wave (W, in seats ) = Wave speed x seconds
In 1.80 seconds, the width of the wave is
W (in seats) = 27.8 x 1.80 = 50 seats

A human wave. During sporting events within large, densely packed stadiums, spectators will send a wave (or pulse) around the stadium (the figure). As the wave reaches a group of spectators, they stand with a cheer and then sit. At any instant, the width w of the wave is the distance from the leading edge (people are just about to stand) to the trailing edge (people have just sat down). Suppose a human wave travels a distance of 889 seats...
