Asked by maham237 @ in Mathematics viewed by 327 People

The average walking speed R of a person living in a city of population P in thousands is modeled by the​ function, R(P) = 0.37P + 0.05​, where R is in feet per second. The population of Newport News is 162,000. Find the average walking speed of people living in Newport News.

Answered by maham237 @


Answer: 59.99 feet per second.

Step-by-step explanation:

Given : The average walking speed R of a person living in a city of population P in thousands is modeled by the​ function

R(P) = 0.37P + 0.05 , where R is in feet per second.

If the population of Newport News is 162,000, then the average walking speed of people living in Newport News will be :-

R(P) = 0.37(162) + 0.05=59.99

Hence, the average walking speed of people living in Newport News = 59.99 feet per second.
