Answer :
Mary walks approximately 20 3/4 miles in one day.
To determine the number of miles Mary walks in one day, we divide the total distance of 62 3/4 miles by the number of days, which is 3.
Dividing 62 3/4 by 3, we can express the division as a mixed number: 62 3/4 ÷ 3 = (60 + 2 3/4) ÷ 3.
Simplifying the division, we divide each part separately: 60 ÷ 3 = 20 and 2 3/4 ÷ 3 = 3/4.
Combining the results, Mary walks approximately 20 3/4 miles in one day.
