You can put this solution on YOUR website! on de. 26 2004 an earhquake generated tsunamis off the coast of the island of sumatra. one tsunami struck patong beach in thailand,which was about 250 miles away from the epicenter of the tsunami. another tsunami struck Batticaloa in sri lanka. which was about 900 miles away from the epicenter. both batticaloa and patong were struk at about the same time. if the rate of the tsunami which struck batticaloa was 325 mph greater than that of the tsunami which struck patong find the rates of both tsunamis, use a table and the five step method
-------------------
sum to tha DATA:
distance = 250 miles ; time = t hrs ; rate = d/t = 250/t mph
----
sum to Bat DATA:
distance = 900 miles ; time = t hrs ; rate = 800/t mph
---------------------
Equation:
faster-slower = 325 mph
900/t - 250/t = 325
650/t = 325
t = 2 hrs.
