Question

The scale of a map is 4 cm: 15 km. If the distance on the map between two cities is 7 cm, what is the actual distance?

Answer 1

thx

Explanation:

Answer 2

26.25 km

Explanation:

Step up a portion. Here, 4 cm is to 7 cm as 15km is to x km

4/7 = 15/x

Now solve for x by cross multiplying

4x = 105

x = 105/4 (divide by 4 on both sides)

x = 26.25 km (simplify)
