A river of width 'w' is flowing variable velocity given by v_(r)=v_(0)(1+ (sqrt(3)-1)/(w)y). Where 'y' is perpendicular distance from one bank. A boat is driven such that it moves perpendicular to bank. Velocity of boat in still water is 2V(0) Time taken to reach other bank

A river of width 'w' is flowing variable velocity given by v_(r)=v_(0)

1.	A river of width 'w' is flowing variable velocity given by v_(r)=v_(0)(1+ (sqrt(3)-1)/(w)y). Where 'y' is perpendicular distance from one bank. A boat is driven such that it moves perpendicular to bank. Velocity of boat in still water is 2V(0) Time taken to reach other bank
Answer» `(pi w)/(6(sqrt(3)-1)V_(0))` `(w)/(6sqrt(3) - 1 )V_(0))` `(w)/(6(sqrt(3)+1)V_(0))` `(pi w)/(3(sqrt(3)-1)V_(0))` ANSWER :A
