Well, how long will it take you to drive 135 miles at 55mph?
at 55 mph, you're doing 55 miles every hour, so we can simply get the quotient of 135/55 and that's how many hours it'll take you to drive 135 miles at that speed.
![\bf \cfrac{135}{55}\implies \cfrac{27}{11}\implies 2\frac{5}{11}~hours\implies \textit{about 2hrs, 27 minutes}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B135%7D%7B55%7D%5Cimplies%20%5Ccfrac%7B27%7D%7B11%7D%5Cimplies%202%5Cfrac%7B5%7D%7B11%7D~hours%5Cimplies%20%5Ctextit%7Babout%202hrs%2C%2027%20minutes%7D)
so, it takes you that long, however, from 3:15 to 5:00pm there are only 45mins + 60mins or 1hr and 45 minutes, namely 1¾ hr.
so 2hrs and 27 minutes is much later than 1¾ hr, so, no dice, you can't arrive at 5pm, actually you'll arrive around 5:42pm.

Answer:
Step-by-step explanation:
The average rate of change of a function f between a and b (a< b) is :
R =[f(b)-f(a)] ÷ (a-b)
●●●●●●●●●●●●●●●●●●●●●●●●
Let R be the average rate of change of this function
f(6) = 2×6^2 - 7×6 = 72-42 = 30
f(2) = 2×2^2 - 7×2 = 8-14 = -6
R = [f(6) - f(2)]÷ (6-2)
R = [30-(-6)] ÷ 4
R = -36/4
R = -9

The average rate of change of this function is -9
