Answer:
Step-by-step explanation:
Let the number of floors = x
Number of apartments per floor = 4x
4x *x = 100
4x² = 100
x² = 100/4
x² = 25
x =√25
x = 5
Number of apartments on each floor = 4*5 = 20
I do this differently from many people, but the answer is 25 miles. If they walk 5 miles every day, and it’s a 40 day process, you multiply 8 by 5, which equals 40. After that you multiply 5 by 5 and you get 25. Sorry if that’s hard to understand, but the answer is 25.
