Let x=unknown number of miles

40%2F1=x%2F1 Start with the given ratio


40%2F1=x%2F60 Write 1 hour as 60 minutes


%2840%2F1%29%2A60=x Multiply both sides by 60


2400%2F1=x Multiply



So our answer is x=2400


So the ratio is 40 mi/1 min = 2400 mi/1h

40 mi/1 min = ? mi/1h
(40 mi/1 min)(60 min/1 hr) = [40*60 mi]/[1*1 hr] = 2400 mi/ hr.
