Question

. A river flows at 3 m/s and is 300 m wide. A man swims across the river with a velocity of 2 m/s directed always perpendicular to the flow of current (ii) In what direction does he actually move (from the starting point) does he reach the opposite bank .

why the distance is taken 150m ...
x= 150x3=450

ans - 450m ​

Answer 1

Answer:

(i) velocity of man 1

to the bank of river =2m/s

t= d/vmr =300/2 =150sec

(ii) He will actually move along vmg

tano = vmr/vmg =2/3 = o=33.7°

(iii) x=(vrg)t =3×150 =450m
