Question

Aricela is trying to estimate the distance between her house 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 Aricela use to determine the distance, d, between her house and the park?

Answer 1

We have to find the proportion Aricela can use to determine the distance between her house and the park. We know that on a map the scale is: 0.5 in = 2 miles and the distance between the house and the park on the map is 2.75 in. The proportion is: 0.5 in / 2 miles = 2.75 in / d miles. After that we can cross mukltiply: 0.5 d = 5.5 miles. d = 5.5 : 0.5 = 11 miles. Answer: This proportion is: 0.5 in / 2 miles = 2.75 in / d miles.
