The average walking speed s, in feet per second, of a pedestrian in a city of population p, is approximated by the model below: s(p) = 0.05 + 0.37ln(p) Use the model above to compute the average walking speed of a pedestrian in a city of p = 10000.
a. 0.42 feet per second
b. 2.61 feet per second
c. 3.46 feet per second
d. 4.31 feet per second
