Current Attempt in Progress

Tsunamis are fast$-$moving 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 six$-$story building. One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of $670$ km and traveled a distance of $3460$ km in $4\mathrm{.}39$ h $.($a$)$ What was the speed $($in $\frac{m}{s})$ of the wave? For reference, the speed of a $747$ jetliner is about $250\frac{m}{s}.$ Find the wave's $($b$)$ frequency and $($c$)$ period.
