To find out how long it will take Francesca to ride 8 miles at the same rate she rode yesterday, we first need to determine her rate of riding.

Yesterday, she rode for 30 minutes and covered 6 miles. We can calculate her rate (in miles per minute) using the formula:

\[
\text{Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{6 \text{ miles}}{30 \text{ minutes}} = \frac{1}{5} \text{ miles per minute}
\]

This means she rides at a rate of \( \frac{1}{5} \) miles per minute.

Now, we want to find out how long it will take her to ride 8 miles at this same rate. We can use the formula:

\[
\text{Time} = \frac{\text{Distance}}{\text{Rate}}
\]

Substituting the known values:

\[
\text{Time} = \frac{8 \text{ miles}}{\frac{1}{5} \text{ miles per minute}} = 8 \times 5 = 40 \text{ minutes}
\]

Therefore, it will take Francesca **40 minutes** to ride 8 miles today.
