Question
The speed of current is 10 km/hr. If the speed of the
boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to cover 336 km in downstream. Find the original speed of the boat in still water (in km/hr).Solution
ATQ, Let the speed of the boat in still water be ‘x’ km/hr. According to the question, (x + 8 + 10) = 336 / 7 Or, x + 18 = 48 So, x = 48 - 18 = 30 km/hr
