vladimir2022 [97]

Answer:

T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

Step-by-step explanation:

Given

w = headwind

T = time

Model:

<em />T(w) = \frac{300}{530 - W}<em> -- This was not properly presented in your question</em>

Required

What does T(110) means

First, we calculate T(110):

Substitute 110 for w in T(w) = \frac{300}{530 - W}

The expression becomes

T(110) = \frac{300}{530 - 110}

T(110) = \frac{300}{420}

T(110) = 0.714<em> -- approximated</em>

<em>T(100) represents that the plane flies against the wind at 110mph for 0.714 hours</em>
