While preparing the material-order review for the marina restroom shell, a accessible ramp has a 24 ft run at 8.33% slope. What rise over the run is required in inches?
Correct Answer
B) 24.0 in.
Convert run to inches and multiply by the slope percentage expressed as a decimal.
Why This Is the Correct Answer
Convert run to inches and multiply by the slope percentage expressed as a decimal.
Why the Other Options Are Wrong
Option A: 2.0 in.
2.0 in. is below the supported result for accessible ramp; it likely omits allowance, conversion, coverage, or final round-up.
Option C: 30.0 in.
30.0 in. is above the supported result for accessible ramp; it likely double-counts allowance, uses the wrong unit, or rounds too early.
Option D: 24.7 in.
24.7 in. is above the supported result for accessible ramp; it likely double-counts allowance, uses the wrong unit, or rounds too early.
