While driving in an exotic foreign land you see a speed limit sign on a highway iliat reads 180,000 furlongs per fortnight. How many miles per hour is this? (One furlong is i mile, and a fortnight is 14 days. A furlong originally referred to ilie length of a plowed furrow.)?
Obviously you will have to calculate speed. Please calculate it and provide me an answer. I'll match it with my own solution.
