We have a map with a scale of 1 inch is equal to 40 miles.
The problem tells us that on this map we have two cities that are two and 1/4 inches apart.
So, now that we know that the map scale is 1 inch that is equal to 40 miles and we have two cites that 21/4 miles apart we set up an equation to help us determine the miles apart the two cities are.
40 miles/in x 2 1/4 inches/1 = ? We cross cancel to inches units which will leave us miles as units and then solve the equation by multiplying the two numbers; 40 x 2 1/4.
This will give us the answer.
