Not sure where to post this or if this can be solved, but I couldn't figure it out because math and physics are clearly not my strength :) I am writing a book where one of the characters has the ability to speed her travel through time. Basically, she is in a type of warp bubble, for lack of a better word. From her perspective, everyone is moving slower, but she is still able to interact with the world around her. On the flip side, she moves very fast according to everyone else. From her point of view, an object that is moving at 58m/s looks like it is moving at 1m/s. What I am wondering is how fast she would move if she were to walk (average walking speed 1.389m/s) or run (average running speed 4.47m/s)? Is it a 1 to 1 ratio, as in, would she walk 58m/s + (her speed)? This doesn't seem correct to me, but I'm not sure how I would calculate her speed. I realize this is fictional, but I am a stickler about being historically and mathematically accurate in all of my writing and any help or just a calculation would help me immensely. Thank you in advance for your help.
