Answer:
Your friend sees you moving at 0.25 m/s upstream.
Step-by-step explanation:
Remember that relative velocity is the velocity of an object in relation to another object. In this example, your friend sees you moving with respect to the river with a relative velocity (Vr) of:
Vr = Yor Velocity (Vy) - The river Velocity (Vriver) =
Vr = 1.25 m/s - 1 m/s = 0.25 m/s
