The slope of a railway is expressed as a percent and is called the grade of the road. At the Royal Gorge, in Colorado, an inclined railway takes visitors down to the arkansas river. If the grade is 175% and the vertical drop of the railway is 1015 feet, what is the horizontal change of the railway?

Answer 1

ok so slope is rise/run
\[1.75=\frac{rise}{run}=\frac{1015}{run}\]

Answer 2

We need to solve
\[1.75=\frac{1015}{run}\]
for run

Answer 3

run is the horizontal change

Answer 4

okay and then?

Answer 5

is that all??

Answer 6

\[1.75 run=1015\]

Answer 7

yes just divide both sides by 1.75

Answer 8

and that's the answer??

Answer 9

whatever 1015/1.75 is yes

Answer 10

105?

Answer 11

that is the horizontal change?

Answer 12

yes

Answer 13

i get 580

Answer 14

1015/1.75 is what i did

Answer 15
