Question

A snail travels at a rate of 2.58 feet per minute.
a. Write a rule to describe the function.
b. How far will the snail travel in 9 minutes?





d(t) = t + 2.58; 11.58 ft


d(t) = 2.58t; 23.22 ft


d(t) = 9t; 23.22 ft

Answer 1

To address the problem regarding the distance traveled by a snail, we can follow the steps outlined below:

### a. Write a rule to describe the function.
The distance \( d(t) \) that the snail travels can be expressed as a function of time \( t \) in minutes. Since the snail travels at a constant rate of 2.58 feet per minute, the rule can be written as:

\[
d(t) = 2.58t
\]

### b. How far will the snail travel in 9 minutes?
To find the distance the snail travels in 9 minutes, we can substitute \( t = 9 \) into the function:

\[
d(9) = 2.58 \times 9
\]

Now, calculating that:

\[
d(9) = 2.58 \times 9 = 23.22 \text{ feet}
\]

Therefore, the answers are:
- The rule to describe the function is \( d(t) = 2.58t \).
- The distance the snail will travel in 9 minutes is 23.22 feet.

The correct answer from the options provided is:

**d(t) = 2.58t; 23.22 ft**.
