Please help me with a quick number pattern question

[salecucksyoosemock]

Ryan's first period class begins at 8:10 and ends at 9:00. His second period class begins at 9:05 and ends at 9:55. His third period class begins at 10:00 and ends at 11:05. If this pattern continues, when does Ryan's fourth period class begin and end?

How long do the classes last - each?

Write it out!

8:10 - 9:00, 9:05 - 9:55

When does the third class start? When does the third class end?

When does the fourth class start? When does the fourth class end?

"His third period class begins at 10:00 and ends at 11:05."
This doesn't fit pattern. Is "11:05" correct?

Yes, that is what has me stumped.

Ryan's missed his fourth period class, because..

Ryan's fourth period class began at 10:55 and his third period teacher ran over!!
