Hi bam, thank you for the question. That might have been a [Google search](https://www.google.com/search?q=km+to+miles), or maybe I took the reciprocal of the conversion from miles to kilometers provided [in the textbook](https://openstax.org/books/college-physics/pages/c-useful-information#import-auto-id2371652). In any case, we want to know how many miles are in how many kilometers in order to create a fraction with miles on the top, and kilometers on the bottom. Writing the fraction as $\\dfrac{1 \\textrm{ mile}}{1.609 \\textrm{ km}}$ would also work - test it out to confirm! All the best, Shaun
