Two Ways To Solve
First Way: Unit Conversion
%2890miles%2Fhour%29%2A%281hour%2F60minutes%29=%281.5mi%2Fmin%29
Then times 20 minutes by new units
20min%2A%281.5mi%2Fmin%29=30+miles
Second Way:
Notice that 20 minutes is 1%2F3 of a hour. So in 1%2F3 the time you go 1%2F3 the distance which is 90%2A%281%2F3%29=30+miles
