Frieda walks 6 feet per second, a pace which is 1/3 as fast as Evita's pace. If Evita's pace is twice as fast as Pablo's then how many feet does Pablo walk in an hour?

A. 129,600

B. 64,800

C. 32,400

D. 3,600

E. 540

The rate of Frieda is 6 feet per second, and that rate is 1/3 as fast as Evita’s rate. Thus,

1/3(Evita’s rate) = 6

Evita’s rate = 18 feet per second

Since Evita’s rate is twice as fast as Pablo’s rate, Pablo’s rate is 18/2 = 9 feet per second.

Thus, Pablo can walk 9 x 3,600 = 32,400 feet in an hour.

(Note: 1 hour = 3,600 seconds)

Answer: C
