> think you forgot a space between " " in the line for kmh<10. Do i have it right ?

Partially. My example is however correct.

The first IF statement adds one blank (space).
The second IF statement adds one blank.

If the value is < 10 km/h, then BOTH 'if' statements will be excuted adding a total of two blanks. If the value is > 9 and < 100, then only the FIRST 'if' statement is excuted adding only one blank.
