Joe's boat leaves the harbor and heads straight for Treasure Island, which is 39 degrees North of West. Joe travels 23 km to reach the island. Moe leaves a little while later and first heads North to try and get a glimpse of some dolphins (that had earlier been sighted by her friends). Moe travels 11 km due North. At this point she is disappointed at having seen no dolphins and heads straight for Treasure Island. What is the total distance Moe travels from the harbor to the island?
