A body travels uniformly a distance of

\left( {20 \pm 0.1} \right)\,\,m

in time

\left( {2.0 \pm 0.02} \right)\,\,s.

The velocity of the body is

View answer and explanation

Correct option: D

\left( {10 \pm 0.1} \right)\,\,m{s^{ - 1}}

Option D (

\left( {10 \pm 0.1} \right)\,m{s^{ - 1}}

) is the closest to the correct answer because it correctly calculates the velocity and its associated uncertainty using error propagation.
