One car length for each ten miles per hour.
The interval between two occurences is TIME.
interval interval
The interval between two notes that are a diminished third apart is two half steps.
The difference between two pitches is called an interval. It refers to the distance between two musical notes in terms of pitch.
The contour interval between two contour lines marked 10m and 20m is the difference in elevation between the two lines. In this case, the contour interval is 20m - 10m = 10m. Therefore, the contour interval is 10 meters.
If you are in one of the cars thenmake a note of the time when the first car passes some fixed point,make a note of the time when the second car passes the same point,the distance between the two cars is the speed of your car multiplied by the time interval.

Time
The interval between two notes that are a melodic 2nd apart is one whole step.
The time between two events is the interval between them.
This depends entirely on how close they are, and what number they have written on them. Sometimes they can be minimal distances apart, in which case they're liable to be quite a substancial gap between the 2 lines, in comparison to them being 4 centimetres apart on the map, in which case it would be a very minimal rise/decline.
The difference in elevation between two contour lines that are side by side is the contour interval. The contour interval is the vertical distance between two adjacent contour lines on a topographic map.
