Question 1038639
<font face="Times New Roman" size="+2">

The percent of grade is the rise or fall per 100 horizontal units. In other words, a 5% grade would mean the road rises or falls 5 in (or feet or miles) for every 100 in (or feet or miles) horizontally travelled.

One question per post please.
