Q. Barbara decided to take a bicycle trip to the observatory. The road has a vertical rise of 306306 feet for every 18001800 feet of horizontal change. In percent, what is the grade of this road?\newlineThe grade of the road is □% \square\% . (Simplify your answer.)
  1. Calculate grade formula: Calculate the grade of the road by using the formula for grade, which is (vertical rise/horizontal change)×100(\text{vertical rise} / \text{horizontal change}) \times 100.
  2. Perform division and multiplication: Perform the division and multiplication to find the grade percentage.
