Time the POST spent from DATE_ENTRADE to DATE_SAID

Sum of minutes that POSTO spent: 

SELECT SUM(TIMESTAMPDIFF(MINUTE,DATA_ENTRADA,DATA_SAIDA)) AS tempo_total_posto FROM 'OS' WHERE POSTO = 'SÃO PAULO'
  

Overall average time that all POSTS take from DATE_ENTRATE to DATA_DATE

Overall average spend time spent 

SELECT AVG(TIMESTAMPDIFF(MINUTE,DATA_ENTRADA,DATA_SAIDA)) AS media_geral FROM 'OS'
