What does the odometer of an automobile measure?

What can you say about the motion of an object if its speed-time graph is a straight line parallel to the time axis?

What can you say about the motion of an object whose distance-time graph is a straight line parallel to the time axis?

An artificial satellite is moving in a circular orbit of radius $42250 \, km$. Calculate its speed (in $m s^{-1}$) if it takes $24 \, h$ to revolve around the Earth.

During an experiment, a signal from a spaceship reached the ground station in five minutes. What was the distance of the spaceship from the ground station? The signal travels at the speed of light, that is, $3 \times 10^{8} \, m \, s^{-1}$.

$A$ racing car has a uniform acceleration of $4 \,m s^{-2}$. What distance (in $m$) will it cover in $10 \,s$ after start?
