Question
A boat covers 30 km downstream and 18 km upstream in a
total of 6 hours. If the speed of the stream is 2 km/h, then what is the speed of the boat in still water?Solution
ATQ, Let speed of boat in still water = x km/h Downstream speed = x + 2 Upstream speed = x - 2 Given, 30/(x + 2) + 18/(x - 2) = 6 Try option x = 8: 30/10 + 18/6 = 3 + 3 = 6 So, x = 8 km/h Hence, the correct answer is 8 km/h.
