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

Use a proportion (5/200 = 7/x) so you would multiply 7 and 200 and divide that answer that by 5 and that's your answer (280 miles)

Answer 2

`(5)/(200) = (7)/(x) \\ 5x = 1400 \\ x = 280`

therefore, the actual distance is 280 miles.

(sorry, idk the rule for it)
