Zane is a dangerous fellow who likes to go rock climbing in active volcanoes. One time, when he was 20 meters below the edge of a volcano, he heard some rumbling, so he decided to climb up out of there as quickly as he could. He managed to climb up 4 meters each second and get out of the volcano safely.
