Question

a map distance of 5 inches represents 200 miles of actual distance. suppose the distance between two cities on the map is 7 inches. what is the actual distance between the two cities? write the rule you used to find the actual distance

Answer 1

Set up a proportion:

5/200 = 7/x

Cross multiply:

200 * 7 = 5 * x

1400 = 5x

Divide 5 to both sides:

x = 280
