Describe a real-life situation in which you need to know a slope.

You are solving for the incline of the slope of the mountain to find out what kind of equipment you bring. You find that part of the mountain has a slope of 1, which meant you had to bring pickaxes, ropes, and other vertical climbing gears. On the other side, you see that the slope is only 1/3. This is much more easier to climb, and seems to be the better option of the two.
