Caroline and her friend Rita are on vacation with Caroline’s family to the Great Salt Lake in Utah. On the first day of their trip, they raced down to the shoreline of
the lake and rented a canoe. When they got to the shoreline with the canoe, they stopped short in amazement. People were floating in the lake with their heads far out of the water, even though they weren’t making any swimming motions. They put the canoe in the water, got in, and started paddling. Almost immediately, the canoe tipped over. The water was not deep, so they up righted the canoe and set out again. The same thing happened. They never had this problem when they canoed on fresh water lakes.
