# Relative Velocity Example

A student is swimming across a stream with velocity ⃗Vs= 6 m/s [E]. The water is moving downstream with velocity⃗Vw= 4 m/s [S]. What is the velocity of the student relative to another student sitting on the west bank of the river?

How long does it take to cross the river?

How far downstream does the swimmer go?
