Answer 1

They say that 2 inches on the map equals 25 miles in real life.
That means that 1 inch on the map equals how many miles in real life?

... [time for you to think] ...

That's 12.5 miles. (simply 25 / 2 = 12.5).

So one inch on the map is equal to 12.5 miles in real life.
Starting from this....

So 1 inch on the map is equal to 12.5 miles in real life.
So 2 inches on the map is equal to 25 miles in real life. (2x12.5)
So 3 inches on the map is equal to 37.5 miles in real life. (3x12.5)
So 4 inches on the map is equal to 50 miles in real life. (4x12.5)
So 19.2 inches on the map is equal to <....> miles in real life (19.2 x 12.5).

For you to fill in the <...> using the steps I gave you.
