Another option:

Format Column C as Number, then use the formulas shown:


         A           B          C
1      In        8:00 AM	
2      Out      12:00 PM     =(B2-B1)*24   ------->  4.00
3      In        1:00 PM	
4      Out       5:15 PM     =(B4-B3)*24   ------->  4.25
                             =SUM(C2,C4)   ------->  8.25
