Vector word problem: resultant velocity | Vectors | Precalculus | Khan Academy

Keep going! Check out the next lesson and practice what you’re learning: https://www.khanacademy.org/math/prec... When an object, say, a boat, travels at a certain velocity, and the medium through which it travels, say, a river, has its own velocity, we can find the resultant velocity of the object by adding the two velocities. In this example, we find the resultant velocity vector of a boat.
