Distinguish between speed and velocity.

Under what condition(s) is the magnitude of average velocity of an object equal to its average speed?

What does the path of an object look like when it is in uniform motion?

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 × 10⁸ ms^-1.
