Solution

The correct option is A $\leq$
Given the maximum allowed speed of a car $= 80$ miles/hr.

$∴ v \leq 80$ miles/hour

Q. At a certain instant in time, the number of cars, N, traveling on a portion of a certain highway can be estimated by the formula

N = \frac{20 L d}{600 + s^{2}}

where L is the number of lanes in the same direction, d is the length of the portion of the highway, in feet,and s is the average speed of the cars, in miles per hour. Based on the formula, what is the estimated number of cars traveling on a
