| what does the number on the exit ramp mean. |

Normally it means the miles you've clocked on the interstate, within that state. Normally runs south to north, on vertical interstates, ie exit 1 on a north bound highway is the southern most exit. In Alabama, exit 365 would be your northern most exit, just prior to crossing into TN. On east -west interstates, exit one is usually the eastern most exit. I believe they have standardized this on the US interstate system, but it wasn't more than 10 years ago that on some Pennsylvania roads, the exit numbers were just a numerical progression, with no relationship to the relatvie distance traveled. I haven't driven through another state that numbered exits like PA used to though.
Google is quicker at answering these types of questions than GD though, should speed up your homework in the future. Also likely to quickly get confirming responses, rather than  responses.
