Given
A plane is going to travel 510 miles with a planned speed of 260 mph; however, the flight will have an average headwind of x mph the entire time meaning the plane is flying against the wind. The time, T, in hours, of the flight, is a function of the speed of the plane x can be modeled by T(x)=510/260-x
Answer
A)
![\begin{gathered} T\mleft(x\mright)=(510)/(260-x) \\ T(90)=(510)/(260-90)=(510)/(170)=3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/3btbolhqu3oq09o6l433wa9qcgys6a39j6.png)
B)
When x = 290 denominator is zero T(x) in infinity which is asymptotic
