Question 214920: A ski-lift that runs to the top of a hill has a rise to run ratio of 4/5. The horizontal distance from the bottom of the lift to the center of the mountain is 6000 ft. How high is the hill? If necessary, round your answer to the nearest tenth of a foot and label it ft.. Answer by jim_thompson5910(35256) (Show Source):
Since the rise to run ratio is 4/5, this means that the rise is 4 while the run is 5. In other words, if you are at the ground level, and you want to move up the hill, you simply go up 4 feet while walking toward the hill 5 feet. Visually, this is shown as going up 4 units and going 5 units to the right.
Because we know that the "distance from the bottom of the lift to the center of the mountain is 6000 ft", we can set up the proportion: (where 'x' is the height of the mountain)
Start with the given equation.
Multiply both sides by 6000
Multiply
Simplify
So the answer is
This means that the height of the hill is 4,800 feet.
