Sara walked 1 mile from her home to her school and 625 feet from her school to the libary. if she followed the same path to go from the libary to her home, how far did she walk altogether?

2 miles and 1250 feet

Step-by-step explanation:

by walking from her home to the library, she is walking 1 mile and 650 feet. she is now the same distance as she walked to get to the library, so the distance must be doubled.

1 mile x 2 = 2 miles

625 x 2 = 1250

2 miles 1250 feet

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
