Answer:
the second one +1.5 m/s
Step-by-step explanation:
to find the velocity you need to find the slope of the two points then just put it into the time (s) and position (m) terms which equals +1.5 m/s
Answer:
Step-by-step explanation:

Keep the first fraction, change division to multiplication and find the reciprocal(multiplicative inverse) of the second fraction

To determine the coordinates of the midpoints of a line segment, get the average of the both the abscissas and ordinates. In this example, the average of the abscissas is 22 and that of the ordinates is -4. Thus, the midpoint is (22, -4).
