# An express train travels 80 kilometers per hour from Ironton to Wildwood. A local train, traveling at 48 kilometers per hour, takes 2 hours longer for the same trip. How far apart are Ironton and Wildwood?

$s = \frac{d}{t}$

$s \times t = d$

Since the distance is equal, we can state the following, where x is the time in hours the express train takes.

$48 \left(x + 2\right) = 80 x$

$48 x + 96 = 80 x$

$96 = 32 x$

$3 = x$

It takes 3 hours to make the trip.

$80 \times 3 = 240$

The distance is $240$ kilometers.
