Step 2: Determine what unit your answer should be in (miles) Step 3: Write a conversion factor to achieve desired unit (1 mile/5,280 ft.) Step 4: Multiply and divide as needed Step 5: Cancel units Generic Formula for conversion: Given unit × (desired unit/given uni t) = desired unit 7,690 ft. × (1 mile/5,280 ft. ) = 1.46 miles 1.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
