If you have to use the + instead of the :
then:
=LEFT(C1,FIND("+",C1)-1)/24+MID(C1,FIND("+",C1)+1,255)/(24*60)+LEFT(C2,FIND("+",C2)-1)/24+MID(C2,FIND("+",C2)+1,255)/(24*60)

and format C3 as [hh]:mm

Does anyone know of a formula to add cells with training times in a
hour+minute format? Example: Cell C1 is 1+12 (1 hour and 12 minutes traning)
and cell C2 is 0+55 (55 minutes of training) equals cell C3 3+07 (3 hours and
7 minutes total training (i.e.: 1+12 and 0+55 = 3+07).
