help me please
 

I have this file :
00962798578964 600 00962785985764
00962798578964 110 00962786897532
00962798578964 61 00962776898523
00962798578964 111 00962795225325
00962798578964 45 00962777965862
00962798578964 55 00962799548155


- $1 : number of mobile doing calls to another numbers
- $2 : time of calls in secondes.
- $3 : number of reciver call.


I need code do this :
Print time of calls in mintues as this :
600/60 = 60
110/60= 2
61/60=2
111/60=2
45/60=1
55/60=1
*hint : if time of call < 60 sec then time= 1 mintue

*hint in this file we have three companys (in $3) numbers:
-0096278*******
-0096277*******
-0096279*******

*I want to print sum of time (in mintue) for each company alone :
Example :
600/60 + 110/60 = 12 min
Example :
61/60 + 45/60 = 3 min
Exactly I want to print :
12 min
3 min
3 min
