Question
A boat goes 8 km an hour in still water, but takes twice
as much time in going the same distance against the current. The speed of the current (in km/hour) is :Solution
Let the speed of the current be x kmph. According to the question, 8/(8 – x) = 2 ⇒ 16 – 2x = 8 ⇒ 2x = 16 – 8 ⇒ x = 8/2 = 4 km/hr
