.

Take the difference of speeds v(4) - v(0) and divide this difference by 4 seconds.

That's all.

slowed down at a variable rate, decreasing his speed as time increased, so you have a decreasing line that begins at a point at (0, 5) and ends at (4, 1),
the average rate of change is equal to a slope=%281-5%29%2F%284-0%29=-4%2F4=-1
so, the average rate of change is -1%28m%2Fs%29
