Perimeter of a square = 4 * each side
so, in the given case 4 * lenght of each side = 272 yards
so, each side = 272/4 = 68 yards
Answer:
1 mile
Step-by-step explanation:
1 hour = 3 miles
20 minutes is 1/3 of an hour, so he walks 1 mile
Rewrite the fractions to have a common denominator:
1/3 = 2/6
1/2 = 3/6
Now rewrite the full numbers as improper fraction:
5 2/6 = 32/6
1 3/6 = 9/6
Subtract:
32/6 - 9/6 = 23/6
Now rewrite as 3 5/6
Answer: 3 5/6
