Question
The speed of a boat in still water is 5 km/hr and the
speed of the stream is 1.5 km/hr. A man rows to a place at a distance of 22.75 km and comes back to the starting point. The total time taken by him is:Solution
Rate downstream = (5 + 1.5) kmph = 6.5 kmph Rate upstream = (5 – 1.5) kmph = 3.5 kmph According to the question, Time = Distance/Speed Hence, Required time = 22.75/6.5 + 22.75/3.5 = 3.5 + 6.5 = 10 hours
