I put 220 divided 3 and The answer is 7.3
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.
Answer:
7 hours
Step-by-step explanation:
$247.50 - $45.00 (how much he charges for the first hour) = $202.50

Hoped this helped
If you work out the difference between 2 and 7 you will get 4 so you add 4 each time.
3=12
4=16
5=20
