As a joke, someone recently proposed the Furlong/ Firkin/ Fortnight (FFF) system of measurement based on antiquated units. There are 8 furlongs in a mile, and a fortnight is 14 days; a firkin is 70 pounds. (a) a snail can travel 75.0 furlongs/ fortnight. What is its speed in cm/sec? (b) How far in meters would it travel in 2.00 days? (c) If a snail weighs 2.00 grams, how many snails would it take to make a firkin at sea level?
