Answer: ![24^{\circ}](https://tex.z-dn.net/?f=24%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given
River is flowing from south to North with a velocity of ![u=1\ m/s](https://tex.z-dn.net/?f=u%3D1%5C%20m%2Fs)
Motor boat traverses the river from east to west at a speed of ![v=2.5\ m/s](https://tex.z-dn.net/?f=v%3D2.5%5C%20m%2Fs)
South component of boat velocity must compensate the river velocity in order to travel in west direction.
![\therefore v\sin \theta=u\\\\\Rightarrow 2.5\sin \theta=1\\\\\Rightarrow \sin \theta=\dfrac{2}{5}\\\\\Rightarrow \theta=23.57^{\circ}\approx 24^{\circ} \text{south of west}](https://tex.z-dn.net/?f=%5Ctherefore%20v%5Csin%20%5Ctheta%3Du%5C%5C%5C%5C%5CRightarrow%202.5%5Csin%20%5Ctheta%3D1%5C%5C%5C%5C%5CRightarrow%20%5Csin%20%5Ctheta%3D%5Cdfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%5CRightarrow%20%5Ctheta%3D23.57%5E%7B%5Ccirc%7D%5Capprox%2024%5E%7B%5Ccirc%7D%20%5Ctext%7Bsouth%20of%20west%7D)
