Solution Steps
To find the rate at which Yesenia needs to drive to reach Chicago in 3 hours, we can use the formula for speed, which is distance divided by time.
Step 1: Identify the Given Values
We are given the distance \( d = 168 \) miles and the time \( t = 3 \) hours.
Step 2: Use the Speed Formula
To find the rate \( r \) at which Yesenia needs to drive, we use the formula for speed:
\[
r = \frac{d}{t}
\]
Step 3: Substitute the Values
Substituting the given values into the formula:
\[
r = \frac{168 \text{ miles}}{3 \text{ hours}} = 56 \text{ mph}
\]
Final Answer
Thus, the rate at which Yesenia needs to drive is \\(\boxed{56 \text{ mph}}\\).
