Given that an object moves from the position +16 m to the position +47 m in 12 s. Now we need to find about what is its total displacement and what is its average velocity.
We know that displacement is the object's overall change in position.
So total displacement is given by:
Displacement = (+47) - (+16) = +31
Now velocity is given by ratio of displacement and time so final answer for velocity will be :
Which is approx 2.6 m/s.
