If a man rows at the rate of 25 kmph in still
water and his rate against the current is 5.5 kmph, then the manrsquo;s rate along the current is:Solution
Let manrsquo;s speed downstream be x kmph. Manrsquo;s rate in still water = (x + 5.5)times; frac12; kmph 25 = (x + 5.5)times; frac12; kmph 50 = (x + 5.5) kmph x = 50 ndash; 5.5 = 44.5 kmph
