Note: These Challenge Questions coincide with the Spring 2006 Reports Challenge Question #3 From: by way of Jane Duden Journey North <lthurber@anwsu.org> Date: Mon Mar 13 2006 - 13:55:55 EST Challenge Question #3: "If a gray whale and her calf swim more slowly, how long do you estimate their journey takes if they swim a total of 6,000 miles from Mexico to Alaska?" I multiplied 3 miles times the number of hours in a day - to make 72 miles. This is what an average whale could easily do in one day. Then we took 6000 miles and divided that by 72 to see how many days an average whale would need to swim that distance. That would be about 83 days. So, if the gray whale and her calf swim more slowly than that, they would take over 83 days! If they swim 2 mph, it would be 125 days.
