Step 1
Given: - Distance traveled = 3700 km = 3,700,000 m - Time taken = 5.6 hours = 5.6 * 3600 seconds = 20,160 seconds Speed = Distance / Time Speed = 3,700,000 m / 20,160 s Speed ≈ 183.53 m/s Show more…

Tsunamis are fast-moving waves often generated by underwater earth- quakes. In the deep ocean their amplitude is barely noticeable, 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 750 km and traveled a distance of 3700 km in 5.3 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.
