The Hernandez family left for a vacation at 8 a.m. By noon they were 208 miles away from home and the family stopped to get lunch. Calculate the average rate of change. I don't know what the rate of change is... I mean, I got that they were traveling at 52mph is that the answer?

Answer 1

Some examples of "Average rate of change" involve calculating miles per gallon, miles per hour, etc. In this problem, you are calculating the average rate of speed which is distance/time:

208/4hours = 52 mph.

Therefore, you are correct.
