Note that, after t seconds, the boat travels 1.65t m towards the short and the boat floats 1.05t m down stream.
Then, the distance that the boat actually travels is:
D = √[(1.65t)^2 + (1.05t)^2] = 1.96t.
Therefore, the speed of the boat is:
v = D/t = 1.96t/t = 1.96 m/s.
I hope this helps!

searching on the course of u... keep in mind at a particular time v would might want to go back and forth hostile to u.s. consequently u<v foe the round vacation to even b plausible because if u wuz >v.....then the boat does no longer b able to oppose the present.
