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?
He travels 1450-100=<<1450-100=1350>>1350 feet vertically
So he travels 1350*2=<<1350*2=2700>>2700 feet horizontally
#### 2700
