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 + 0.05, where r is in feet per second. The population of Wilkes-barre is 48,000. Find the average walking speed of people living in Wilkes-barre

The average walking speed is 1.48 feet per second

Step-by-step explanation:

we have

where

r is average walking speed

p is the population  in thousands

In this problem we have

----> because p in the equation is in thousands

substitute the value of p in the equation

using a calculator

v,jhvljh,b.b; hk; ljujb,vuvccklokll; k,m,km,

step-by-step explanation:

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
