Casey and David both ride all-terrain vehicles on trails every weekend for fun each month KC rides for a total of 2x hours at an average speed of x miles per hour David rides for more hours a month in KC but at an average speed that is 3 miles per hour less than Casey's average speed write the standard form of the function which describes the total distance of miles that David rides each month
