Initial position, u = 10 m

Final position, v = 5 m

Change in time, ∆t = 5 s

We know that, velocity = ∆x / ∆t

where, ∆x is the displacement and ∆t is the change in time.

∆x = v - u

∆x = 5 m - 10 m

∆x = -5 m

Velocity = ∆x / ∆t

Velocity = -5 m / 5 s

Velocity = -1 m/s

Therefore, B: -1 m/s is the correct answer. A negative velocity means the object is traveling in the other direction.
