I was given data in the following format:

00 10 20 30 40 50
0 25 30 41 43 36 38
1 40 56 52 38 35 20
2 25 19 38 44 46 50
3 52 58 48 56 50 48

Is there an easy way to convert it to the following format:

0:00 25
0:10 30
0:20 41
0:30 43
0:40 36
0:50 38
1:00 40
1:10 56, etc.

Any suggestions would be apprecated.
