30.) B and D seem to be the positive so basically the highest velocity. B starts from 0 to infinity and D starts from -1 to infinity because neither of those lines would meet, they would just continue forever growing. The two least would be A and C.

Answer:

A. 5 m/s

Explanation:

From the graph, for the first 2 seconds, the graph is a straight line meaning that the slope is a constant.

Average speed of an object is the rate of change of position. Here, the position of the object changes from 0 m to 10 m for a time interval of 2 seconds.

The change in position ( $\Delta x$ ) and time interval ( $\Delta t$ ) are given as:
