No.  A unit rate would be something like 6 2/3 miles per hour, which is the same speed as above.

suppose the population of a town is growing exponentially. the population was 4,636 in 2008 and grew to 5,508 in 2018. what is t
Sloan [31]
<h2>94.93</h2>

Step-by-step explanation:

   The standard equation used to model a exponential growth is given by f(t)=Ae^{Bt}

   Given two data points, which are both explicitly a function of time, it is easy to solve the two equations,

4636=Ae^{2008B} ,5508=Ae^{2018B}

Dividing the second equation by the first,

\frac{5508}{4636}=\frac{Ae^{2018B} }{Ae^{2008B} }

e^{10B}=\frac{5508}{4636}

10B=ln(\frac{5508}{4636} )=0.17235

B=0.017235

Substituting in first equation, A=4.32645\textrm{x}10^{-12}

Growth model : f(t)=(4.3265\textrm{x}10^{-12} )e^{0.017235t}

Growth rate=ABe^{Bt}=94.93

∴Approximate growth rate as of 2018 = 95
