Tsunamis are fastmoving waves often generated by underwater earthquakes. In the deep ocean their amplitude is barely noticable, but upon reaching shore, they can rise up to the astonishing height of a sixstory building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 747 km and traveled a distance of 3830 km in 5.03 h. (a) What was the speed (in m/s) of the wave? For reference, the speed of a 747 jetliner is about 250 m/s. Find the wave's (b) frequency and (c) period.
change units to m and second.
speed= distancetraveled/time
frequency=speed/wavelength
period= 1/frequency.

a) 3830km * 1000m/km / ( 5.03h * 3600s/h)
b) 3830km * 1000m/km / (5.03h * 3600s/h) / (747km * 1000m/km)
c) 1 / (3830km* 1000m/km / (5.03h*3600s/h) / (747km * 1000m/km))
