9 and 3 fourths is 9 3/4 3 and 3 eights is 3 3/8 So now you have to compare 9 3/4= 3 3/8 days Y= 1 day Y represents the unknown rate Change the mixed fractions to improper fractions 4 times 9 plus 3=39/4 8 times 3 plus 3= 27/3 39/4= 27/3 days Y= 1 day Cross multiply 27/3 x Y=39/4 x 1 27/3 Y=39/4 Divide both sides by 27/3 39/4 ÷ 27/3 39/4 x 3/27 The answer is 13/12 miles which is 1.083 miles Hope I helped. Good luck
