Not really because I don't have a formula to use to solve for anything, i tried a binomial equation but that came out wrong, I retraced to see if I wasn't converting the units but I was, I tried putting everything into miles per second but I keep getting stuck when trying to solve for t so that...

I've decided that the v=d/t is not the way to go and that (vi) initial velocity is vi- 4.5mph=vf or final velocity (vf) = vi + 4.5 mph. and the time is t-9. going 1 mile gives me initial distance= 0 final distance= 1 initial velocity(vi)= vf-4.5 mph final velocity(vf)= vi+4.5 time for (vi) mph=...

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 4.5 mi/h, the time to go one mile decreases by 9 s. What was your original speed? I've been working on this for 2 hours, I can't seem to get the formula...
