Samantha is trying to estimate the distance her school and the park. On a map with scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in. Which proportion can Samantha use to determine the distance, d, between her school and the park?

Answer 1

Samantha can set up the following proportion:

0.5 in. / 2 miles = 2.75 in. / d

Then, she can cross multiply to solve for d:

0.5 * d = 2 miles * 2.75

0.5d = 5.5 miles

Now, divide both sides by 0.5 to solve for d:

d = 5.5 miles / 0.5

d = 11 miles

Therefore, the distance between Samantha's school and the park is 11 miles.
