Question
A boat can cover 40 km upstream and 60 km downstream in
13 hour. Also it can cover 50 km upstream and 72 km downstream in 16 hour. Find the speed of boat in still water.Solution
Let upstream speed = a And downstream speed = b Now, => 40/a + 60/b = 13 ------- (i) And, => 50/a + 72/b = 16 ------- (ii) Solving (i) and (ii) we get, => a = 12 and b = 5 Speed of boat in still water = (a + b)/2 = (12 + 5)/2 = 8.5 kmph
