Quizplus · Accepted Answer

The distance from New York to San Francisco is approximately 2,900 miles. Assuming an average step length of about 2.5 feet, it would take roughly 2,000 steps to walk a mile. Therefore, the total number of steps would be around 2,900 miles * 2,000 steps/mile = 5,800,000 steps, which is closest to ten million.
