The peak Tyler climbs is at point P on the north end of a pond. After Tyler finishes his climb, you walk 1600 m from P along a road to an intersection at X. Then you walk another 600 m along that road to your campsite at C. Finally, you walk 400 m due north to a restaurant at R to get dinner. While you're eating, you tell Tyler that you can figure out the distance across the pond from north to south, PD.
