Rare 1918 "Jenny" stamp, depicting a misprinted, upside-down Curtiss JN-4 "Jenny" airplane, was sold at auction for $525,000. A collector uses a simple magnifiying glass to examine the "Jenny," obtaining a linear magnification of 2.4 when the stamp is held 2.70 cm from the lens. Calculate the focal length of the magnifying glass?
