If the contour interval is 50 meters on this map, then the line between 500 and 600 has an elevation of 575 <

525 <

550 <

The line between 500 and 600 has an elevation of 550.

Explanation:

The contour interval represents the vertical difference between the contour lines. This is for better orientation on the map, easier calculating of elevation, as well as for an easier understanding of the relief. In this case, we have lines that are set at 500 meters and 600 meters of elevation, but there is also a line between them.

The line between, or rather the contour line between them, can easily be found out as to what elevation it is set on. We have information that the contour interval on the map is 50 meters, so we can do this either by adding 50 on 500 or minus 50 out of 600, anyway we will get the correct result.

500 + 50 = 550

600 - 50 = 550

We get a result of 550, meaning that the contour line between 500 meters and 600 meters is set at 550 meters of elevation.
