Can you please explain what formula I need to do to solve the following problem:

If 3 laps = 5/8 mile, how many laps needs to be completed to run 3 miles?

Don't look for "formulas" to do these kind of questions, use ratios, one of the most powerful tools of math

3 laps = 5/8 mile

x laps = 3 miles

so

3/x = (5/8)/3

cross-multiply

(5/8)x = 9

x = 9(8/5)

=14.4 laps
