Q). Assume Port San Juan (entrance near Port Renfrew) and Sooke Harbour entrance are 58 km apart. Based this distance and data in Table ES1 (considered above), what is the average speed in km/hr of the tsunami wave traveling between these two points?. Distance is in km. Time difference from Table ES1 is in minutes, and we want wave speed in km/hr. __________

Explanation / Answer
here tsunami arrival time of both the points are given in mins and distance is in km. sowe have toconvert the mins in to the hours :
port san juan : 0.58 hrs
sook harbour: 1 hr
now the distance between them is 58 km
port san juan : 58km/ 0.58 hrs = 100 km/hr
sook harbour: 58km/1 hr = 58 km/hr
The average speed is about = (100+58)/ 2 = 79 km/hr
