A race pilot's average rate of speed over a 720mile course is inversely proportional to the time in minutes t the pilot takes to fly a complete race course. The pilot's final score s is the average speed minus any penalty points p earned.
1. Write a function to model the pilot's score for a given t and p (Hint: d = rt)
2. Graph the function for a pilot who has two penalty points.
3. What is the maximum time a pilot with 2 penalty points can take to finish the course and still earn a score of at least 3?

Best ResponseYou've already chosen the best response.2For part 1, use the given hint. \[d=rt\] notice that we have \(d=720\) here, so \[720=rt \implies r = \dfrac{720}{t}\]

Best ResponseYou've already chosen the best response.2`The pilot's final score s is the average speed minus any penalty points p earned.` \[s = r  p\] plugin the value of \(r\) above

Best ResponseYou've already chosen the best response.2\[s=\dfrac{720}{t}p\] thats the function for part1

Best ResponseYou've already chosen the best response.2good, for part2, simply plugin \(p=2\) and graph the function

Best ResponseYou've already chosen the best response.0so for part 3 do I just look for the maximum point on the graph?

Best ResponseYou've already chosen the best response.2nope, for part3, simply plugin \(s=3\) in the function and solve \(t\)

Best ResponseYou've already chosen the best response.2\[3=\dfrac{720}{t}2\] solve \(t\)

Best ResponseYou've already chosen the best response.0so that's the maximum time

Best ResponseYou've already chosen the best response.2Yes thats the maximum time acceptable anything greater than that will reduce the score
