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
