Answer:
The average speed is of 12 meters per second.
Step-by-step explanation:
The average speed can be given by the difference in position divided by the different in time.
Average speed, between 5 and 10 seconds.
d(t) = 0.8t²
d(5) = 0.8*(5)² = 20
d(10) = 0.8(10)² = 80
Times: 5 and 10 seconds. So
v = (80 - 20)/(10 - 5) = 12
The average speed is of 12 meters per second.
