I have a bunch of problems like this one.

can any one lend me a hand?

A corpse is found at 7:00am his temperature is 85 degrees Fahrenheit.

By 8:30 am his temperature is at 82 degrees Fahrenheit.

What time did he die?

*Normal body temp is 98.6 degrees Fahrenheit.

*Room temp. is 74 degrees Fahrenheit.

Thank you.
