|Divide its magnetic heading by 10, round it to the nearest whole number and you will usually get the runway number.
For example, if the magnetic heading is 345° then 345/10 = 34, 5.
So the runway number will be 35 which will be a runway used for landings (and takeoffs) to the north.

|How it is 13 and 31? Explain it.|

|S 45° E means 90 + 45 = 135 135/10 = 13.5 so its nearest value 13 and 360-45=315 315/10= 31.5 near value 31.|

|The difference between the runway number is always 18.|

|How to solve this? Please explain.|

The direction for both numbers 13 and 31 will be the same,
Just draw a line with 130° clockwise, and then draw the line 310°. You will see both are in the same direction in two opposite coordinates.

|Runway numbers are determined by rounding the compass bearing of one runway end to the nearest 10 degrees and truncating the last digit.|

|Why to subtract 360 -45°?|
