20points+brainliest Read the excerpt about Annie Londonderry from Chapter 4 of Wheels of Change.

1 Finally, on June 25, 1894, she was off. 2 She pedaled to New York, over good roads and bad, in eight days, but with stops to rest and earn money, she didn't reach Chicago, Illinois, until September 24. 3 It had taken her three months to travel approximately 1,300 miles, and she had more than 20,000 miles left to cover.

4 Annie Londonderry thought about giving up, but instead made some changes, trading her heavy skirts for bloomers and her Columbia bike for a much lighter men's Sterling. 5 She also decided to head east, riding back to New York and crossing the Atlantic on an ocean liner. 6 Annie traveled largely by ship through Europe, the Mideast, and Asia, taking short cycling trips at various points along the route. 7 She reached San Francisco, California, on March 23, 1895, and pedaled to Chicago to complete the journey.
