Q. Explorer is caught in a whiteout (in which snowfall is so thick that the ground cannot be distinguished from the sky) as returning to base camp. He was supposed to travel due north for 5.2 km, but when the snow clears; he discovers that he in fact travelled 7.6 km at 56o north of due east. How far (in km) must he now travel to reach base camp?
