(hint: think about where the hotspot is. (5 points) 13) the map tells us that there is 11.2 square miles of lava as of july 9th, the entire big island has an area of 4028 square miles. divide 11.2 by 4028 then multiply that number by 100 to calculate what percentage of the big island has been covered by the latest eruption. % of the big island. (round it to 3 decimal places) (5 points) 14) now that a channel has been established lava is reaching the sea from fissure 8, in roughly 13 minutes. let's calculate how fast it's moving in miles per hour 1. convert 13 minutes to hours. divide 13 minutes by 60 minutes/hour 13 min 60 min/bx brs (5 points) 2. it is roughly 8 miles from fissure 8 to the sea. divide this distance by the travel time you got above to get the speed the lava is flowing in miles per hour speeda distance - 8milesspeed of the lava mph. (5 points) time 15) does that number seem fast or slow to you? do you think that lava would be flowing that fast if it wasn't in a channel and was just flowing over open ground? (5 points)
