Answer :
Final answer:
Correct option is d) .Traveling through the continental crust at 100 km/hr would theoretically take 30 minutes to an hour based on the average thickness. However, in reality, it is not possible to travel through solid rock.
Explanation:
To calculate how long it would take to travel through the continental crust at 100 km/hr, we first need to know the thickness of the continental crust. The average thickness of the continental crust is about 30-50 kilometers. Therefore, to travel through it at 100 km/hr would take roughly 30 minutes to an hour, assuming it were possible to travel in a straight line through the crust at that constant speed.
However, the answer to the question is actually d) Not possible to travel through. This is because the continental crust consists of solid rock, and one cannot drive or travel through it in the same way one would travel on a road. This problem is more of a theoretical nature designed to think about speeds and distances, rather than a real-world scenario.
