The velocity of boat relative to water is `4 m/sec` . The velocity of water relative to ground is `8m/sec`. In what direction boatman aims the boat to cross the river in minimum drift distance method.

sqrt(3) times the velocity of a boat on still water is twice the velocity of current of a river. At what angle , with respect to the current, should the boat be steered so as to cross the river in least distance ?

The velocity of a boat in still water is 10 m//s .If water flows in the river with a velocity of 6 m//s what is the difference in times taken to cross the river in the shortest path and the shortest time.The width of the river is 80 m .
