Answer:

Step-by-step explanation:

Distance = Speed x Time and you need speed so the equation is

D divided by T = S

Cutwright 35 laps divided by 84 min .... 42mph

Evans 42 laps divided by 96.6 min ... 43 mph

Loza 38 laps divided by 102.6 min ... 37 mph

Vanyuwa [196]

Here it is given that the width is x ft and total length of the fence is 2400 ft .

Let the length be y ft

So we have

$2(x+y) =2400
\\
x+y=1200
\\
y = 1200 -x$

Let A represents area, and area is the product of length and width .

So we get

$A = x y$

Substituting the value of y, we will get

$A = x (1200-x)= 1200x -x^2$

Second part

The area is maximum at the vertex, and vertex is

$x = - \frac{1200}{2(-1)} = 600 feet$

And

$y=1200-x = 1200-600 = 600 feet$

And that's the required dimensions .
