Question

Barbara decided to take a bicycle trip to the observatory. The road has a vertical rise of 192 feet for every 1600 feet of horizontal change. In percent, what is the grade of this road? Simply your answer

Answer 1

The grade of the road is 12%.

Step-by-step explanation:

To find the grade of the road, we need to calculate the ratio of the vertical rise to the horizontal change, and then express it as a percentage.

The ratio of the vertical rise to the horizontal change is 192/1600.

To express this ratio as a percentage, we multiply it by 100.

So the grade of the road is 12%

Answer 2

It is given that rise is 192 over run of 1600 feet.

Then the grade is given by

`\text{Grade}=(192)/(1600)=0.12`

Hence grade percentage is

`0.12*100=12`

HEnce the answer is 12%
