Question
What is the speed of boat in still water?
Statement I: The boat can cover 24 km downstream distance in 4 hours. Statement II : Speed of the stream is Two-fifth the speed of boat in still water. Statement III: The boat can cover 24 km upstream distance in 8 hours.Solution
Let speed of boat = u, and stream = v From I: u + v = 24/4= 6 km/hr From II: v = 2u/5 From III: u - v = 24/8= 3 So solving I and II ‘u’ can be found. Similarly by solving II and III and by solving I and III
