Please use code tags when posting data/code/logs etc.

Inset a second line with
Code:
0-30/5 11 * * * my-command

or if it does complain when closing/saving the crontab, try:

Code:
0,5,10,15,20,25,30 11 * * * my-command

Assuming that the cron on your system recognizes the /5 notation, the above would run my-command every 5 minutes from 07:00 through 11:55. Presumably, you need to change the above to:
Code:
 */5  7-10 * * * my-command

and add one of the lines zaxxon suggested to take care of 11:00 through 11:30.

So, according to the man page, the last field before the command to be executed specifies the days when the job is to be run. As in:
Code:
0,5,10,15,20,25,30 11 * * 1-5 my-command
0,5,10,15,20,25,30,35,40,45,50,55 7-10 * * 1-5 my-command
