In river crossing problems why we consider velocity of man wrt water as velocity of man in still water?
@ pratyay it is beacuse of the easy calculation purpose , if we will take the water as moving , then the calculation will be bulky and that effect the value of the velocity of the swimmer also , and also , in most of the ques the velocity in which water is moving , not mentioned , so, in that case for simplicity of calculation we are assuming it as still water . EVEN IN ONE YEAR JEE ADVANCED ASKS THIS QUES AS THAT OF MOVING WATER .. hope it clears your doubt
