Question

The scale of a map is 2 inches = 5 miles .Anamari looks at the map to plan a driving trip to her aunts house. According to the map l, she will drive 6.4 inches south along highway 75, then 7.8 inches east along 653. How many miles will anamari drive to her aunts house?

Answer 1

Anamari will drive 35.5 miles to her aunts house.

Explanation:

Let the miles will Anamari drive to her aunts house be x

The scale on the map is 2 inches = 5 miles

Now she walks 6.4 inches south and 7.8 inches east

So she has walked = 6.4 + 7.8 = 14.2 inches

According to the scale

2 inches = 5 miles

then

14.2 inches = x

By cross multiplication

2x = (5) (14.2)

2x = 71

`x = (71)/(2)`

x = 35.5
