A particle moves along a straight line along the $x$-axis. Its position ( $\mathrm{x}$ ) versus time $(\mathrm{t})$ graph is shown in the figure [ $x$ in meters and $t$ in seconds]. It's average speed during this motion is
  1. $0.4 \mathrm{~ms}^{-1}$
  2. $1.0 \mathrm{~ms}^{-1}$
  3. $0.8 \mathrm{~ms}^{-1}$
  4. $0.6 \mathrm{~ms}^{-1}$

Solution

$\begin{aligned} & \text { Average speed }=\frac{\text { Distance travelled }}{\text { time }} \\ & =\frac{4 \mathrm{~m}}{5 \mathrm{~s}}=0.8 \mathrm{~m} / \mathrm{s}\end{aligned}$
