You can put this solution on YOUR website!
(1 inch)/(50 miles) = (4.5 inches)/(x miles)

1/50 = 4.5/x

x = 50*4.5

x = 225

So 4 ½ inches on a map represent 225 miles in real life.

Convert to kilometers by multiplying by 1.609344 to get:

225*1.609344 = 362.1024


Answer: 4 ½ inches on a map represent 362.1024 kilometers in real life.
