1. Osaka , Japan - 0630
Hawaii , USA - 1100
Los Angeles , USA - 1530
2. 5200 miles approx distance was travelled by the tsunami waves from Japan to Los Angeles.
3.It took between 9-10 hrs for the wave to travel the distance.
4.Speed basic formula is (Distance/Total Time)-
5. The above calculated speed is not the actual speed of tsunami at any instantaneous point but it varies from place to place.In places without any obstruction the speed is very high while in regions of continents and islands the speed slows down but the average speed gives us a fair bit of idea on how fast it travels and how fast it can reach other regions.
6.The debris arrived late on the offshore because different types of items including cars or building materials , even boat etc . All these items have different buoyancy and they all travel with the help of currents of the pacific ocean. So at times only few materials arrive which seem to have the buoyancy to catch up with the currents of pacific ocean. There it took a lot of time for the debris to travel from japan to los angeles.
