Ingat!

$1 space cm equals fraction numerator 1 over denominator 100.000 end fraction km 1 space detik equals fraction numerator 1 over denominator 3.600 end fraction jam$

maka :

$table attributes columnalign right center left columnspacing 0px end attributes row cell 200 space bevelled cm over detik end cell equals cell open parentheses 200 cross times fraction numerator 1 over denominator 100.000 end fraction divided by fraction numerator 1 over denominator 3.600 end fraction close parentheses space bevelled km over jam end cell row blank equals cell open parentheses 2 over 1000 cross times 3.600 close parentheses space bevelled km over jam end cell row blank equals cell 72 over 10 space bevelled km over jam end cell row blank equals cell 7 comma 2 space bevelled km over jam end cell end table$

Jadi, table attributes columnalign right center left columnspacing 0px end attributes row cell 200 space bevelled cm over detik end cell equals cell 7 comma 2 space bevelled km over jam end cell end table
