Answer:
64 3/16 miles
Explanation:
Total distance walked = 16 3/4 miles = 67/4 miles (converted to improper fraction to help with division later)
number of days walked = 4 days
Miles walked per day = total distance walked ÷ number of days
= 16 3/4 ÷ 4
= 67/4 ÷ 4
= 67/4 x 1/4
= 67/16
= 64 3/16 miles
