Question
Speed of a boat in still water to speed of boat in
upstream is 12:7. If the boat can travel 340 km in downstream in 5 hours, then find the time taken by the boat to cover 16 km in still water.Solution
Let speed of boat in still water and speed of boat in upstream be ‘12x’ km/h and ‘7x’ km/h, respectively. Speed of stream = 12x – 7x = 5x km/h Speed of boat in downstream = 12x + 5x = 17x km/h So, 17x = 340/5 = 68 Or, x = 4 Speed of boat in still water = 12 × 4 = 48 km/h Desired time = 16/48 = 20 minutes
