A vehicle is inclined 26 units up a ramp whose slope is in the ratio 12:5. How many units higher is the vehicle than the ground level?
Correct answer: A. 10
- A. 10
- B. 13
- C. 24
- D. 26
Explanation
The vehicle is inclined 26 units up the ramp. We know that for a ramp length of 13 units (from our slope ratio calculation), the vertical height is 5 units. Since the actual ramp length the vehicle traveled is 26 units, which is twice the calculated ramp length (26 / 13 = 2), we need to scale the vertical height by the same factor. The incline is typically expressed as a ratio, with the most common standards being: 1:12 (ADA Standard): For every 1 inch of rise, you need 12 inche... 4. Calculate the actual height: Actual height = Vertical height (from slope ratio) * Scaling factor Actual height = \(5*2=10\) units. The incline is typically expressed as a ratio, with the most common standards being: 1:12 (ADA Standard): For every 1 inch of rise, you need 12 inche... Therefore, the vehicle is 10 units higher than the ground level. The final answer is 10
