A steam boat goes across a lake and comes back (1) On a quite day when the water is still and (2) On a rough day when there is uniform air current so as to help the journey onward and to impede the journey back. If the speed of the launch on both days was same, in which case it will complete the journey in lesser time

View answer and explanation

Correct option: A

Case (1)

Option A (Case (1)) is correct because the time taken is lesser when the water is still, as the air current increases the time for the return journey more than it decreases the time for the onward journey.
