Answer 1

Answer: 868 miles

Explanation:

Given: The scale from a map to actual distance is 2.5 cm to 620 miles.

i.e. 1 cm on map =
`(620)/(2.5)\text{ miles}=248 \text{ miles}`

If the distance on the map between Chicago and Boston is about 3.5 cm.

Then, the actual distance between them =
`3.5* 248 \text{ miles}=868 \text{ miles}`

Hence, the approximate distance between Chicago and Boston = 868 miles.
