Getting hours open/inProgress/done in the current sprint

[Max Bower]

Hi!

I'm looking for an easy way to get some basic information about the currently active sprint:

- What is the sum of the hours of sub-Tasks that are still not closed but in this sprint?
- What is the sum of the hours of sub-Tasks currently in progress in the current sprint?
- What is the sum of the hours of sub-Tasks closed in this sprint?
- What is the sum of the hours estimated to complete the sprint (Sum of all hours of all SubTasks that havent been closed at sprint start)?

Is there a way to get this was basic JIRA functionallity? Reporting/JQL?
