How long did it take to build one automobile on the Ford assembly line due to increased productivity?

The correct answer reflects the significant impact of the assembly line on automobile production efficiency. The introduction of the assembly line by Henry Ford revolutionized manufacturing by breaking down the automobile construction process into smaller, repetitive tasks, which greatly reduced the time needed to build a car.

The assembly line allowed for the use of specialized tools and encouraged a flow of work that capitalized on the speed of individual workers completing specific tasks. This method streamlined production and brought the time required to manufacture a complete vehicle down to around 93 minutes. The ability to produce cars quickly led to lower costs for consumers, making automobiles much more accessible to the public.

This approach to manufacturing not only transformed the automotive industry but also had a broader influence on production methods across various industries, ultimately shaping modern manufacturing practices.
