A steam boat goes across a lake and comes back
(1)On a quiet and calm day when the water is still
(2)On a rough day when there is a uniform current so as to help the journey onwards and to impede the journey backwards.
With the same speed of launch on both days the times taken to complete the two-way journey on the quiet and rough day are t1 and t2. THEN
1) t1 < t2
2) t1=t2
3) t1>t2
4) t1>_<t2
plz give answer by solving and expanation
