Given:
d(t) = 0.8t²
d(5) = 0.8*5² = 0.8 * 25 = 20
d(10) = 0.8*10² = 0.8 * 100 = 80
Average speed = distance traveled / time of travel
Average speed = 20 meters / 5 seconds = 4 meters per second
Average speed = 80 meters / 10 seconds = 8 meters per second
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps the average speed in meters per second between 5 and 10 seconds.
