For this case we have the following inequality:

From here, we define the variable x.
x: number of minutes remaining to finish the race.
From here, we clear the value of x.
We have then:

Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.
Answer:
x < 22.5; Sam has fewer than 22.5 minutes left to finish running.
Step-by-step explanation:
there must be some additional information missing (like the domain of the function), because just as it is written here, the function f(x) would not have any limitations, and its range would be -infinity < y < +infinity.
so, it is impossible to tell you which answer option is correct.
because again, based on the given information, none of these options is correct.
Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be
. Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.
