Wonky watches

Mr Ashworth's watch loses two minutes every hour. 

Miss Dilks' watch gains one minute every hour. 

They both set their watches from the radio at 6:00 am, then start their journeys to school. 

When they arrive (at the same time) their watches are 9 minutes apart. 

At what time (the real time) did they arrive at school?
How did you work it out?
