Agroup of friends moored their boats together and fell asleep on the lake. unfortunately, their lashings came
undone in the night, and they drifted apart. gerald’s boat traveled due west along with the current of the lake
which moves at a rate of 1/2 mi/hr and helena’s boat was pulled southeast by some pranksters and set drifting at a
rate of 2 mi/hr.
a. if the boats came untied three hours ago, how far apart are the boats?
b. if gerald drops anchor, then in what direction should helena travel in order to reunite with gerald?
