Final answer:
The first time he put a bike together, it took a long time. His improvement in speed and skill can be attributed to the learning curve.
Step-by-step explanation:
The first time he put a bike together, it took a long time. His improvement in speed and skill can be attributed to the learning curve. The learning curve is a concept that illustrates the relationship between the time invested in a task and the improvement in performance over time. As individuals repeatedly perform a task, they become more proficient, leading to increased speed, efficiency, and skill. The initial slow pace when assembling the bike reflects the early stages of the learning curve, while the subsequent improvements denote the process of acquiring experience and expertise, resulting in a quicker and more skillful execution of the task.
