Lucas lives nearby a calm stretch of the Cowichan River. Today the speed of the current near Lucas's house is 1 km/h. Lucas puts his canoe in the water and paddles 5 km downstream, and then he turns around and paddles 6 km upstream to his grandfather's house, who lives on the river. The whole trip takes Lucas 3 hours. What would Lucas's canoe speed be on the still waters of Cowichan Lake
