The fuel efficiency increases for speeds up to 25 mph when it reaches a relative maximum efficiency of 54 mpg. The fuel efficiency then decreases for speeds between 25 mph and 41 mph, when it gets down to 37 mpg. Above 41 mph, efficiency increases again until it reaches 48 mpg at 60 mph. Finally the fuel efficiency rapidly decreases for speeds greater than 60 mph until lev king off at 17 miles per gallon. (This is from glencoe algebra 1 page 62)
