Answer:
6. 300/4 feet per hour or feet/hour
7. 90/10 feet per second or feet/sec
Try simplifying the fractions though.
Step-by-step explanation:
average rate of change just means the change in distance per the change in time (per meaning divided by). what is the change in distance? 700-400 = 300. change in time is 6-2 = 4 hours. so 300/4
Same thing, change in distance is 100 - 10 feet and change in time is 40-30 seconds so the average rate of change is 90/10 feet per second
