ATQ, we can say that We have given the difference between Downstream speed (Ds) and Upstream Speed (Us) is 6km/hr Then, Ds - Us = 6…….eq1 Let the speed of Downstream(Ds) of boat be [Speed= distance/time] = 72/4 = 18km/hr Now, putting the Ds value in eq1 we will get the value for Us. = 18 – Us = 6 18 – 6 = Us 12km/hr = Us Therefore, the speed of boat will be = (1/2) x (18 + 12) = (1/2) x 30 = 15km/hr
