A snail travels at a rate of 2.58 feet per minute. Write a rule to describe the function. How far will the snail travel in 9 minutes?
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
d = r t
d = ???
r = 2.58 feet / minute
t = 9 minutes
d = r t
d = 2.58 9
d = 23.22 feet
Edit
===
You wanted a rule. It is d = r t
d = 2.58 * t
Answer:
\(f(x)=2.58x\)
It will travel 23.22 feet in 9 minutes.
Step-by-step explanation:
Given,
The snail travels at a rate of 2.58 feet per minute.
The distance covered by it in one minute = 2.58 feet,
Thus, the distance covered by it in x minutes = 2.58x
Let f(x) represents the its distance in x minutes,
\(\implies f(x)=2.58x\)
Which is the required function,
For x = 9,
\(f(9)=2.58\times 9=23.22\)
Hence, it will travel 23.22 feet in 9 minutes.
