The formula W = 0.35 ln P + 2.74 models average walking speed, W, in feet per second, for a resident of a city whose population is P thousand. Find the average walking speed for people living in New York city with a population of 7323 thousand

Answer 1

W(7323)=5.85 ft/s

You need to substitute for P=7323 as:
W(7323)=0.35ln(7323)+2.74=5.85 ft/s

WOW....seems quite fast!
