Answer:
442 miles
Step-by-step explanation:
Given
To properly solve this question, I illustrate some given parameters using attached image
From the image, apply Pythagoras theorem
Differentiate w.r.t time (t)
Divide both sides by 2
From the question, we have that the plan travels are 510mi/h.
This implies that:
So, we then calculate the value of x when the distance (y) is 2mi i.e.:
Apply Pythagoras theorem
So, the expression becomes:
<em>Hence, the distance is 442 miles</em>
