To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:
- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).
- Swap x and f(x).
- The result is the inverse of the original
function .

Apply that on your function
Answer:
0.26 minutes
Step-by-step explanation:
So if you want to solve this, you need to make all the units the same first. What you first need to work on is the rate, since what it is asking is minutes given distance in feet.
We know that there are:
5280 ft in a mile
60 minutes in an hour
We then convert the rate knowing this:
In short, the car is traveling 3,828 ft every minute.
To determine how many minutes it will take for the car to travel just remember that:
Now we plug in what we know and solve what we don't know:
