Final answer:
Olympus Mons is more than 20 kilometers tall, and nearly three times the height of Mt. Everest, which is approximately 8,800 meters. Therefore, the approximate height of Olympus Mons would be roughly 26.4 kilometers.
Step-by-step explanation:
The question is inquiring about the height of Olympus Mons, the tallest mountain on Mars, in comparison to Mt. Everest on Earth. While the given figure from Figure 1 is not directly presented in this exchange, additional supplied information indicates that Olympus Mons is more than 20 kilometers tall, and nearly three times the height of Mt. Everest. To provide the student with an accurate approximation based on Earth's metrics, we will use the fact that Mt. Everest is approximately 8,800 meters (or 8.8 kilometers) tall. Since Olympus Mons is said to be almost three times taller than Mt. Everest, we can calculate its height as roughly 26.4 kilometers (3 x 8.8 kilometers).
