Question

I am having difficulty setting up the unit fractions, I believe there should be 3 total, but I am not getting a logical answer when I work through the problem.

Answer 1

1 km = 0.621371 miles

so 5.067km = 3.1484 miles

That's one unit fraction

3.1484 miles / 225 mph = 0.139 hours to go around once

is a second unit fraction

then you can multiply that by 60 to get minutes 0.139 x 60 = 8.34 minutes
