Question
A boat goes 65 km in upstream in 5 hours and takes 4
hours to complete a distance of 20 km in downstream. Find the speed of boat in still water.Solution
Speed of boat in still water = (D + U)/2 Upstream speed (U) = 65/5 = 13 km/hr Downstream speed (D) = 20/4 = 5 km/hr Speed of boat in still water = (13 + 5)/2 = 18/2 = 9 km/hr
