The average walking speed r of a person living in a population P in thousands is modeled by the function, r(p) = 0.37 ln p + 0.0

Veseljchak [2.6K]

Answer:

The average walking speed is 1.48 feet per second

Step-by-step explanation:

we have

$r(p)=0.37ln(p)+0.05$

where

r is average walking speed

p is the population in thousands

In this problem we have

$p=48,000/1,000=48$ ----> because p in the equation is in thousands

substitute the value of p in the equation

$r(p)=0.37ln(48)+0.05$

using a calculator

$r(p)=1.48\ ft/sec$
