33.5 is 2/3 of the 1 p.m. temperature
multiply 33.5 by 3/2 to get 50.25 at 1 p.m
at 10 a.m. it was 8.7 degrees warmer, or 58.95 degrees.
The value of the temperature is what is being asked for. The true temperature requires the Kelvin scale but that is a non-math issue.

As you formulate the problem, it is VERY ILLITERATE description to say that one Fahrenheit temperature
is 1/3 of the other Fahrenheit temperature.

This way to describe temperature is NEVER USED and is considered as a BAD STYLE wording.

And when a person writes or pronounces it, it becomes clear to everybody around, that the person
is unfamiliar with using correct terminology.
