1148 miles all you had to do was add 1748+1748=3496 than 1174+1174=2348 and than you had to subtract the 2 numbers and get 1148. So your answer is 1148 miles.
Let's start his with some trigonometry
Cos60=x/30
X=15
Now we can use Pythagorean therom
15^2+b^2=30^2
B(y)= 25.98
Divide Numerator by Denominator
Since there are 43560 feet in an acre, 285 feet is 0.654% of an acre.
Hope this helps!
