The velocity of river grows in proportion to the distance from it's bank and reaches maximumvalue V_(0) in the middle. Near the banks the velocity is zero. A boat is driven perpendicular to river flow, speed of boat in still water is u ( width of river is w)

Answer»

time TAKEN to CROSS river `W/u`
time taken to cross river `(w)/(sqrt((V_(0)^(2))/(4)+u^(2)))`
Drift is `(V_(0)w)/(2u)`
Drift is `(V_(0)w)/(u)`
