Question

A map has a scale of 2 cm = 25 km. Two cities are 15 centimeters apart on the map. What is the actual distance between the cities?

Answer 1

Answer:

187.5 km

Step-by-step explanation:

For every 2cm there is 25km, So 2cm/25km. Now you are given 15cm, and you need to find the actual distance in km. Set up the fraction 2cm/25km=15cm/Xkm and solve for X using cross multiplication as follows:

2x=25(15), so 2x=375, X=187.5 km.
