On the planet Zardem, the standard unit of time is the Zarsec, or Zs, where 1 Zs = 2.2s. The standard unit of length is the Zardem foot, or ZF. Because Zardemites have particulary large feet, 1ZF = 21 inches. In a foot race a Zardem runner wins the competition with an average speed of 3.5 ZF/Zs. how fast is the runner traveling in units of in/s?
