Question

figure 2. mauna kea
from base to peak, how high is mauna keas peak? (answer choices have been rounded to the nearest tenth.)
○ 4.7km
○ 10.2 km
○ 22.0 km
○ 6.0 km

Explanation:

Step1: Analyze the graph

The y - axis of the graph represents the height in kilometers. The base of Mauna Kea is at 0 km (since it starts from the origin) and the peak is at a height that we can estimate from the graph. Looking at the graph, the peak is between 10 km and 11 km. Among the given options, 10.2 km is the value that is between 10 and 11 and is a reasonable estimate for the height from base (0 km) to peak. The other options: 4.7 km is too low, 22.0 km is way too high, and 6.0 km is also too low.

Answer:

B. 10.2 km (assuming the option with 10.2 km is the correct one among the choices, here we identify the correct option as the one with 10.2 km. If the options are labeled as, say, A: 4.7 km, B: 10.2 km, C: 22.0 km, D: 6.0 km, then the answer is B. 10.2 km)
