Answer: Twin Butte
Step-by-step explanation: Total amount of miles is 68. Half way would be 34 miles. If you count up, you'll end up in Twin Butte.
Si= PTR/100
18 = (3*300*t)/100
18 = 9t
t = 2
2 years
Let each side perpendicular to the river be "x".Then the side parallel to the river is "400-2x".
The formula for Area = width*length
A(x) = x(400-2x)
A(x) = 400x - 2x^2
You have a quadratic with a = -2 and b = 400
Maximum Area occurs where x = -b/2a = -400/(2*-2) = 100 ft. (width)
length = 400-2x = 400-2*100 = 200 ft (length)
