Answer:
P = 20/7 or 2 6/7
Step-by-step explanation:
We want to find the perimeter of a square
P = 4s where s is the side length
s = 5/7
P = 4* 5/7
P = 20/7
We can leave it as an improper fraction or change it to decimal form
7 goes into 20 two times 2*7 = 14 20-14 =6
The mixed number is 2 6/7

19000/3600=5.278
It will take ≈5 hours (5.278)
