3. study the position-time graph for a bicycle. which statement is supported by the graph?
position vs time
position (m)
4
5
2 3
time (s)
a. the bicycle has speed but not velocity.

b. the bicycle is moving at a constant velocity.

c. the bicycle has a displacement of 3 m.

d. the bicycle has no motion.
at monotont velocity will always have

D. The bicycle has no motion.

Explanation:

The graph represents the position of the bike versus time.

From the graph, we see that the position of the bike is constant, at 3 metres  from the reference point, for the whole time: this means that the bike is not moving, so the correct option is

D. The bicycle has no motion.

From a position vs time graph, it is also possible to infer the velocity of the object, which is equal to the slope of the graph: in this case, the line is horizontal, so the slope is zero, which means that the bike's velocity is also zero.
