#17.3"mi"/"hr"#

Explanation:

#("25.4 ft")/("1 sec")xx("1 mi")/("5280 ft")xx("60 sec")/("1 min")xx("60 min")/("1 hr")#

#=(25.4 color(red)(cancel(color(black)("ft"))))/(1 color(blue)(cancel(color(black)("sec"))))xx("1 mi")/(5280 color(red)(cancel(color(black)("ft"))))xx(60 color(blue)(cancel(color(black)("sec"))))/(1 color(green)(cancel(color(black)("min"))))xx(60 color(green)(cancel(color(black)("min"))))/("1 hr")#

#=25.4/1xx("1 mi")/5280xx60/1xx60/("1 hr")#

#=(25.4xx60xx60)/5280 "mi"/"hr"#

#=17.3"mi"/"hr"#
