resultant velocity^2=velocity of man^2+speed of water^2
100=64+speed of water^2
100-64=speed of water^2
36=speed of water^2
6=speed of water
so...., speed of water here is 6km/hr
100=64+speed of water^2
100-64=speed of water^2
36=speed of water^2
6=speed of water
so...., speed of water here is 6km/hr
