The velocity \( (v) \) versus time \( (t) \) plot of a particle is shown in the figure, for a time interval of \( 40\,\mathrm{s} \). The total distance travelled by the particle and the average velocity during this period are, respectively ________.
\( 25\,\mathrm{m} \) and zero
\( 50\,\mathrm{m} \) and zero
\( 100\,\mathrm{m} \) and zero
\( 100\,\mathrm{m} \) and \( 2.5\,\mathrm{m/s} \)
