Answer 1

If you would like to know the proportion Aricela can use to determine the distance, d, between her house and the park, you can calculate this using the following steps:

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

0.5 * d = 2 * 2.75
d = 2 * 2.75 / 0.5
d = 11 miles

The correct result would be B) and D).

Answer 2

To determine the distance between her house and the park, Aricela can use the proportion:

0.5

2.75

=

2

d

. The distance on the map for 2 miles (0.5 in.) corresponds with the distance on the map between Aricela’s house and the park (2.75 inches) and the scaled distance (2 miles) corresponds to the actual distance between Aricela’s house and the park (d).

A the answer would be A.
