What is the speed of boat in still water?
Statement I: It takes the boat thrice as much time to row up than as to row down the same distance in the river.
Statement II: Speed of water is 2kmph.
Statement III: The boat can cover 30 km upstream distance in 10 hours.
Let speed of boat = u, and stream = v From U/V=N+1/N-1=3+1/3-1=4/2=2 From II: v = 2 From III: u – v = 30/10 = 3 So solving I and II ‘u’ can be found. Similarly by solving II and III and by solving I and III
