Question

On the coordinate grid of a map, Josie's house is located at (2, 7). Her school is located at (-5, 5). If each map unit equals one mile, what is the approximate distance from her house to school? A) 2.83 miles B) 4.79 miles C) 7.28 miles D) 12.37 miles

Answer 1

The answer to your question is: 7.28 miles

Explanation:

data

H (2, 7)

S (-5, 5)

1 map unit = 1 mile

Formula

d = √((x2-x1)² + (y2-y1)²)

d = √(-5-2)² + (5- 7)²

d = √ (-7² + -2²)

d = √ 49 +4

d = √53

d = 7.28 units

But

1 unit ---------------- 1 mile

7.28 units ------------- x

x = 7.28 x 1/1 = 7.28 miles
