Question

Quizplus · Accepted Answer

His elevation change is the difference between the starting elevation and ending elevation, which is 11,026 - 9,450 = 1,576 feet. A and D are incorrect because they have the wrong sign (positive instead of negative or vice versa). B is incorrect because it has the wrong magnitude (the elevation change cannot be greater than the starting elevation).
