Question

The grade $x$ of a hill is a measure of its steepness. For example, if a road rises ten feet for every one hundred feet of horizontal distance, then it has an uphill grade of $x=\frac{10}{100}$, or $10 \%$. The braking (or stopping) distance $D$ for a car traveling at $50 \mathrm{mph}$ on a wet, uphill grade is given by

$D(x)=\frac{2500}{30(0.3+x)} .$

(a) Evaluate $D(0.05)$ and interpret the result.

(b) Describe what happens to braking distance as the hill becomes steeper.

(c) Estimate the grade associated with a braking distance of $220$ feet.
