NICET - Highway Construction Inspection Practice Exam

If the cross-slope is 0.04 ft/ft and the horizontal distance is 24ft, what is the vertical distance?

1. 0.96 feet

2. 1.00 feet

3. 1.04 feet

4. 0.88 feet

The correct answer is: 0.96 feet

To find the vertical distance given a cross-slope of 0.04 ft/ft and a horizontal distance of 24 ft, you can use the formula for calculating vertical distance based on the slope and the horizontal run. The cross-slope represents the change in elevation per unit of horizontal distance. Here, a cross-slope of 0.04 ft/ft means that for every foot you move horizontally, there is a corresponding increase in vertical height of 0.04 feet. To calculate the total vertical distance, you multiply the slope (0.04 ft/ft) by the horizontal distance (24 ft): Vertical distance = Cross-slope x Horizontal distance Vertical distance = 0.04 ft/ft x 24 ft = 0.96 ft Thus, the calculation shows that the correct vertical distance is 0.96 feet. This aligns perfectly with the first choice provided.
