Here is my problem as stated:
Driving along a crowded freeway, you notice that it takes a time (t) to go from 1 mile marker to the next. When you increase your speed by 7.8 mi/h, the time to go one mile decreases by 14 seconds. What was your original speed?
I have tried to think of it as if I were going 60 mi/hr it would take me 1 minute to travel 1 mile and then I tried using the conversions I have just learned, but I keep getting stuck. Any help would be much appreciated.
