Final answer:
The average surface temperature on Saturn is -166ºF, which is 46ºF cooler than the temperature near the cloud tops of Jupiter.
Step-by-step explanation:
The question requires us to calculate the average surface temperature on Saturn given that it is 46ºF less than on Jupiter. The background information does not provide us with the exact temperature of Jupiter, but we can use relative comparisons to understand that, generally, as the distance from the Sun increases, the planets have lower surface temperatures. However, we have the necessary information in the question itself that allows us to calculate the temperature difference directly.
Since Saturn is 46ºF cooler than Jupiter and considering the answer choices available, we note that answer choice A - -116ºF cannot be correct as the average temperature near the cloud tops on both Jupiter and Saturn is around 140 K, which is equivalent to -214.15ºF, and Saturn should be cooler than this. Thus, the correct answer is B - -166ºF, which is 46ºF cooler than -116ºF.
