Question 1187445: The temperature of a substance in an experiment changes by -7.5 Fahrenheit from 8 am to 2 pm. At 5 pm, the temperature is 43.5 Fahrenheit. It is 1/3 of what the temperature was at 2 pm. What was the temperature at 8 am of the substance?

In the real world, the problem is nonsense.
We are told that the temperature at 5pm, 43.5 degrees Fahrenheit, is 1/3 of what the temperature was at 2pm. It is nonsense to say one Fahrenheit temperature is 1/3 of another.
It doesn't appear that the problem can be solved using any assumptions about what the actual information is; the rate of cooling between 2pm and 5pm is far greater than the rate between 8am and 2pm.
The problem as posted makes no sense; it can't be solved.
