One day, a smuggling ship was 6 kilometers away from our coastal defense post, and was fleeing at a speed of 750 meters per minute. After hearing the report, the officers and soldiers of our post immediately set off to chase, and 12 minutes later, they were 360 meters away from the smuggling ship. Fired a shot and asked him to stop the ship for inspection. How much faster is my speedboat than the smuggling boat?
某日一艘走私船在离我海防哨所6千米处，正以每分钟750米的速度仓惶逃走，我哨所官兵闻报后立即驾挺出发追赶，12分钟后在离走私船360米处鸣枪责其停船检查．我快艇的速度比走私船快多少？
