An electric train is moving with a velocity of $120 \, km \, h^{-1}$. How much distance will it cover in $30 \, s$ (in $, km$)?

The following table shows the position of Renu, while she is going to her school. Draw a distance-time graph for her motion.

Time	Distance from her home $(km)$
$06:45 \, am$	$0$
$07:00 \, am$	$8$
$01:30 \, pm$	$8$
$01:45 \, pm$	$0$

$A$ motor bike running at $90 \, km \, h^{-1}$ is slowed down to $54 \, km \, h^{-1}$ by the application of brakes over a distance of $40 \, m$. If the brakes are applied with the same force,calculate $(i)$ the total time in which the bike comes to rest and $(ii)$ the total distance travelled by the bike.

What conclusion can you draw from the displacement$-$time graph of a body as shown below?

$A$ car travels $100\, km$ east and then $100\, km$ south. Finally,it comes back to the starting point by the south-east route. Throughout the journey the speed is constant at $60\, km\, h^{-1}$. The average velocity for the whole journey if the time taken is $3.3\, h$ is

The distance-time graph of a body is a straight line inclined to the time axis. The body is in:
