Echo problem physics?

A hunter is standing at 110 m from the base of a steep rock wall. He discharges his rifle towards the wall. The sound from his rifle makes an echo as it bounces back to him from the rock wall.
How long does it take for the first echo to return to the hunter from the opposite wall of the canyon?
