Question
The ratio of the speed of a boat in still water to its
speed in downstream is 6:8. If the difference between the time taken by the boat to travel 288 km each in upstream and in downstream is 3 hours, then find the speed of the boat in still water.Solution
ATQ, Let the speed of the boat in still water and its speed in downstream be '6y' km/h and '8y' km/h. So, speed of the stream = 8y - 6y = '2y' km/h And, speed of the boat in upstream = 6y - 2y = '4y' km/h According to the question, 
Hence, speed of boat in still water is 6y = 12×6 = 72
