Qadha of Salaah Missed while Travelling

Qadhaa of Salaah missed while one was on Safr

Q: I travel daily from Midrand to Witbank +- 110kms daily to work. I need to know whether the salahs I have to perform daily are in the Qasr state and also if I return home and if I have missed my salahs during the day I have to perform Qaza in a Qasr state.

Also if the Juma salah is missed then whether qaza for the fard salah is 2 or 4 rakaat.  (also in above state)
