Respuesta :
As per the unitary method, it take 3 minutes will it take John to reach the flagpole.
The term unitary method in math is defined as in which the value of one article is first obtained to find out the value of any required articles.
Here we have given that John is jogging on a straight jogging trail toward a flagpole at a speed of 500 ft/min. He is currently 1500 feet from the flagpole. And here we have to write an absolute value function that models John's distance from the flagpole after x minutes.
Here let us consider x be the time taken by John to reach the flagpole.
And here we know that
speed = 500 ft/min
height = 1500 feet
Then the absolute function for the given situation is written as,
=> f(x) = 500|x|
Apply the value of f(x) as 1500, then we get
=> 1500 = 500|x|
=> x = 3
