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

A bus starting from rest moves with a uniform acceleration of 0.1 m s^-2 for 2 minutes. Find

(a) the speed acquired,

(b) the distance traveled.

A farmer moves along the boundary of a square field of side 10m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position?

What is the quantity which is measured by the area occupied below the velocity-time graph?

A bus starting from rest moves with a uniform acceleration of 0.1 m s^-2 for 2 minutes. Find

(a) the speed acquired,

(b) the distance travelled.

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