Answer

Step 2: Convert the slope to a percent grade. Multiply the slope by 100 to get the percent grade. So, the percent grade is 0.075×100=7.5%.

Steps

Step 1 ：Step 1: Calculate the slope of the road. The slope is the ratio of the vertical change (the rise) to the horizontal change (the run). So, the slope is 680=0.075.

Step 2 ：Step 2: Convert the slope to a percent grade. Multiply the slope by 100 to get the percent grade. So, the percent grade is 0.075×100=7.5%.
