Linear algebra, math problem solving project

The project involves solving a number of linear algebra problems within a TIME LIMIT OF 5.5 HOURS (however, it will likely take less to solve them).
The time will begin and problems will be sent on an agreed upon time - the latest time to start is 7:30 AM, Eastern Standard Time.
Attached is a SAMPLE set of problems - these are NOT the ones that need to be solved but problems will be very similar.
Please look over the sample and contact me if you would be able to solve a similar set of problems within 5.5 hours starting anytime before 7:30 AM Eastern Standard Time.
