The Mars rover Perseverance just discovered an ancient clock partially sticking out of the sand near its landing site-definitive proof that a technologically advanced civilization once existed on the Red Planet. Scientists have concluded that it is a 12 hour clock remarkably similar to clocks on Earth. The clock is shown in the figure below with the clock hands in the position corresponding to 3 o'clock on an Earth clock. Question for you to answer: From the numbers on the clock determine how many fingers were on each hand of the ancient Martians. (other evidence showed that they possessed two arms with hands at the ends of each arm).
