Question
A boat goes 56 km in upstream in 4 hours and takes 3
hours to complete a distance of 18 km in downstream. Find the speed of boat in still water.Solution
Speed of boat in still water = (D + U)/2 Upstream speed (U) = 56/4 = 14 km/hr Downstream speed (D) = 18/3 = 6 km/hr Speed of boat in still water = (14 + 6)/2 = 20/2 = 10 km/hr
