Mr. H creates a standing wave pattern in a snakey by vibrating it up and down 23 times in 9 seconds in a physics demonstration. Gerald is holding the opposite end of the snakey and is 7 meters away from Mr. H. The snakey is divided into 4 equal- length portions, each inhabited by an antinode. Determine the speed of the wave.
