Question
The speed of current is 22 km/hr. If the speed of the
boat in still water had been 25 km/hr more than the original speed then it would take 5.5 hours to cover 308 km in downstream. Find the original speed of the boat in still water (in km/h).Solution
Let the speed of the boat in still water be ‘x’ km/hr According to the question, (x + 25 + 22) = 308/5.5 Or, x = 56 – 47 = 9
