SOLUTION

From the question, R is the average walking speed of a population of people in a city. and the population of this people P is given as 162,000. The average walking speed has been given by the equation


R(P)=0.37lnP+0.05

To find R, all we have to do is to substitute P for 162,000 into the equation, we have


\begin{gathered} R(P)=0.37lnP+0.05 \\ R(162,000)=0.37* ln162,000+0.05 \\ =0.37*11.9953516+0.05 \\ =4.4382800+0.05 \\ =4.4882800 \end{gathered}

Hence the answer is 4.5 ft/sec to the nearest tenth
