planet A has an average surface temperature of -100F. Planet B has an average surface temperature that is 3/2 times of that Planet A. What is the average surface temperature of Planet A?
You have already said it is 100 F for planet A.
Perhaps you mistyped the question.
It makes no sense physically to talk about one temperature being a certain fraction of another unless absolute (Kelvin or Rankine) temperatures are used. Such temperatures newer go below zero.
The Fahrenheit and Celsius scales do not measure absolute temperature, as you know.
To find the average surface temperature of Planet A, we need to solve for its temperature using the information provided.
Given that Planet B has an average surface temperature that is 3/2 times that of Planet A, we can represent the temperature of Planet B as (3/2) * T (where T is the temperature of Planet A).
We are also given that the temperature of Planet B is -100°F. So, we can set up the equation:
(3/2) * T = -100
To find T, we need to isolate it on one side of the equation. To do this, we can multiply both sides of the equation by the reciprocal of (3/2), which is (2/3):
(2/3) * (3/2) * T = (2/3) * (-100)
Simplifying, we get:
T = (-200/3)
Therefore, the average surface temperature of Planet A is approximately -66.67°F.
