John starts climbing a very steep hill. He travels 1 foot vertically for every two feet horizontally. His elevation increases from 100 feet to 1450 feet. How far does he move horizontally, in feet?
Step-by-step reasoning:
2700
He travels 1450 - 100 = 1350 feet vertically.

So he travels 1350 * 2 = 2700 feet horizontally.

.

Thus, the answer is 2700
