Homework Help: Math

Posted by Hannah on Sunday, November 21, 2010 at 4:57pm.

An object is heated to 90 degrees Celcius and is then allowed to cool in a room whose air temperature is 25 degrees celcius. If the temperature of the object is 75 degrees celcius after 10 minutes, when will its temperature be 50 degrees celcius?

I have no idea how to do this. There are just to many numbers involved!!
