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>
I think the second i didnt make it on paper but its the one that more convence me
2,000 + 1,000 = 3,00 so you would have $2,000 more to get to 3,000
If you would like to know how many times does 50 go into 85, you can calculate this using the following steps:
85 / 50 = 17 / 10 = 1.7
The correct result would be 1.7.
