Answer:
total distance travel by them to cross river is 17.3 m
Step-by-step explanation:
Assume A be the initial position of both person and B as apposite point to A
u component of velocity along SOUTH DIRECTION is 4 cos30 = 0.4330 m/s
v component of velocity along SOUTH DIRECTION is 4 cos90 = 0 m/s
total speed will be = 0.4330 + 0 = 0.4330 m/s
time taken
time taken
component of u in downstream direction = 4 cos120 = -0.25 m/s
component of v in downstream direction = 4 cos 0 = 0.5 m/s
total component in downstream will be -0.25 + 0.5 = 0.25
total distance travel by them to cross river is downstream.
