Question 1016935
We want to go from 85 miles to time, in hours. It looks like this -

{{{(85miles)(hour/mile)=X hours}}}

the key thing is to plug in the right numbers -

{{{(85miles)(1hour/3.7mile)=22.97 hours}}}

miles need to cancel, so even though we say 3.7miles per hour, in this equation, we need 1hr/3.7 miles.
