Answer: $0.024\ \text{miles per sec}$

Step-by-step explanation:

Given

Path is changing according to the function $f(x)=0.03(10x-x^2)$

Rate of change of the elevation is given by the derivative of the function

$\Rightarrow f'(x)=0.03(10-2x)$

At $x=1\ f'(x) \ \text{is}$

$\Rightarrow f'(x=1)=0.03(10-2\times 1)\\\Rightarrow f'(x=1)=0.03(8)\\\Rightarrow f'(x=1)=0.24\ \text{miles per sec}$
