A man must row from a point on one bank to a point 40 m downstream on the opposite bank of a 30 m wide river flowing at 5 m/s. The minimum speed relative to the water with which he can reach that point is:

Answer:

Solution:

$u_{min} = \frac{v _{0} b}{a ^{2} + b ^{2}} = \frac{5 \times 30}{1600 + 900} = \frac{150}{50} = 3 m / s$ .
