1. The problem statement, all variables and given/known data Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next. When you increase your speed by 8.4 mi/h, the time to go one mile decreases by 13 s. What was your original speed? So we know the question is asking for velocity. 2. Relevant equations vi=vf+a*t 3. The attempt at a solution I just can't seem to get the correct setup to solve this problem.
