Question

The scale of a map is 1 cm : 50 mi. What is the distance between two cities that are 4.2 cm apart on the map?

Answer 1

See a solution process below:

Explanation:

To find the actual distance between the two cities using the map, multiply each side of the relationship by `color(red)(4.2)`

`color(red)(4.2) xx 1" cm":color(red)(4.2) xx 50" mi"`

`4.2" cm":210" mi"`

The cities are actually `color(red)(210)` miles apart
