Question

1. the formula v = 1.225√a is used to estimate how far a person can see on a clear day, where v is the visibility in miles and a is the altitude in feet. what is tinas visibility if she is looking out the upper window of a building with an altitude of 1,518 feet? round your answer to the nearest whole number.

Explanation:

Step1: Identify the values

Given formula $V = 1.225\sqrt{a}$, and $a = 1518$.

Step2: Substitute the value of a

$V=1.225\times\sqrt{1518}$.
First, find $\sqrt{1518}\approx38.96$.
Then, $V = 1.225\times38.96$.
$V=1.225\times38.96 = 47.736$.

Step3: Round to nearest whole number

Rounding $47.736$ to the nearest whole number gives $48$.

Answer:

$48$
