In the 1600s, a blacksmith could make a living by
hand-forging horseshoes and nails. A diligent
blacksmith could make one horseshoe in 12 minutes
and a nail in 1 minute. In the 1600s, it would
take the blacksmith 210 minutes to complete a
particular job. With advances in technology, the
blacksmith was able to make a horseshoe in 9
minutes and a nail in 40 seconds, and could
complete the same job in 155 minutes. In the
