Question

A powerful earthquake near the island of Kiribati causes a subsurface sediment slump and initiates a
large tsunami. Tsunami watchers at Hawai'i are immediately notified and begin to evacuate low-lying
areas. The
tsunami has a wave-length of 500 km and the distance separating Kiribati from Hawai'i is
2,800 km. How much time in hours do the Hawaiians have before the tsunami wave arrives? (For the
depth of the ocean, you can assume its mean value).
