Solve the problem.
-In a study by psychologists Bornstein and Bornstein, it was found that the average walking speed w, in feet per second, of a person living in a city of population P, in thousands, is given by the function w(P) = 0.37 ln P + 0.05.
Find the walking speed of people in a city with a population of 1,760,888.
A) 5.37 ft/sec
B) 14.38 ft/sec
C) 3.67 ft/sec
D) 4.52 ft/sec

To find the walking speed, substitute P = 1760.888 (since the population is given in thousands, 1,760,888 becomes 1760.888) into the function w(P) = 0.37 ln P + 0.05. This yields w(1760.888) = 0.37 ln(1760.888) + 0.05 ≈ 5.37 ft/sec.
