Question

The scale of a map is 1 inch: 250 miles. City A is 378 miles from City B. To the nearest tenth, how far is its distance on the map? Show your work. Explain.

Answer 1

This is a proportion question. We can express this as an equation where the answer is x:


`(1)/(250)` =
`(x)/(378)`

From there, you can just cross-multiply and divide to get:


`(1 * 378)/(250)`

A tenth of 250 is 25, so this is roughly
`(375)/(250)` or
`(17)/(10)`, so it'll be approximately 1.7 inches on the map.

Answer 2

Answer: Approx 1.5 inches

Explanation:

Since, according to the question, The scale of a map is 1 inch: 250 miles.

Thus, 1 inches = 250 miles,

⇒1 miles= 1/250 inches.

⇒378 miles=378×1/250 inches.

⇒378 miles = 1.512 inches.

Therefore, If City A is 378 miles from City B.

Then, the distance between city A and B in inches = 1.512 inches ≈ 1.5 inches.
