See a solution process below:

Explanation:

We know there are 5280 feet in one mile so we can write:

#(5280"ft")/"mi"#

And, we know there are 60 minutes in an hour so we can write:

#(1"hr")/(60"min")#

Now we can solve the problem as:

#(180"mi")/"hr" xx (5280"ft")/"mi" xx (1"hr")/(60"min") =>#

#(180color(red)(cancel(color(black)("mi"))))/color(blue)(cancel(color(black)("hr"))) xx (5280"ft")/color(red)(cancel(color(black)("mi"))) xx (1color(blue)(cancel(color(black)("hr"))))/(60"min") =>#

#180 xx 5280"ft" xx 1/(60"min") =>#

#950400"ft" xx 1/(60"min") =>#

#(950400"ft")/(60"min") =>#

#(15840"ft")/"min"#
