Val walks the greater distance. She walks 10 2/5 miles in 4 days:) To find the answer, first you must turn 2 3/5 into a improper fraction and get 13/5. Then multiply it by the 4 days she walks. So do 13/5 x 4/1 and get 52/5. With 52/5 you will divide 52 into 5 and get your answer 10 2/5 :D hope that helps.
