Thanks Damon. Yes, Chris collected $450 is a given. So if Chris collected $450, he walked 25 miles, correct.

I'm having a hard time calculating the miles Lacy walked.

To determine the number of miles Lacy walked, we need additional information or a given relationship between the amounts of money collected and the miles walked by Lacy and Chris. Without this information, it is not possible to directly calculate the miles Lacy walked.

If there is no given relationship, you may want to consider looking for other clues or additional information in the question or context that could help you determine Lacy's total distance.
