Answer :
The Wright brothers flew their first plane in 1903 and the first continental railroad opened in 1869 if you subtract those two you would get 34 years after
Final answer:
Between the completion of the Transcontinental Railroad in 1869 and the Wright brothers' first powered flight in 1903, approximately 35 years passed.
Explanation:
The first continental railroad, known as the Transcontinental Railroad, was completed in 1869, providing a continuous railroad link between the east and west coasts of the United States. The Wright brothers, Orville and Wilbur, achieved the first powered flight on December 17, 1903. To calculate the number of years that passed between these two historic events, we subtract the year the Transcontinental Railroad was completed from the year of the Wright brothers' first flight. The result is 1903 minus 1869, which equals 34 years. However, since we are considering full years that have passed and the flight took place in December, the answer would be closer to 34 full years, making the choice of 35 years the most appropriate for standard rounding conventions.
