Chapter 4: Q. 281 (page 495)

Road grade. A local road has a grade of 6%. The grade of a road is its slope expressed as a percent. Find the slope of the road as a fraction and then simplify. What rise and run would reflect this slope or grade?

Short Answer

Expert verified

The slope of the road is 350. There is a rise of 3 feet run per 50 feet.

Step by step solution

01

Step 1. Given Information

The grade of the road is 6%.

02

Step 2. Determine the slope

  • The slope of the road is same as the grade of the road.

slope=6100=350

  • So, the slope of the road is 350.
03

Step 3. Determine the effect

  • The slope is the ratio of the rise to the run.
  • From the slope, 350it is concluded that there is a rise of 3 feet run per 50 feet.
