Samantha is trying to estimate the distance between her school and the park. On a map with a 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?

0.52.75=2d

d2=0.52.75

0.5d=22.75

d0.5=2.752

1 answer

d = 0.5 x 2.75 / 2

Therefore, Samantha can use the proportion: d = 0.5 x 2.75 / 2
