Final answer:
Marlinton's average elevation is calculated by multiplying Ava's town elevation of -6.4 meters by 2.5, resulting in an average elevation of -16 meters for Marlinton.
Step-by-step explanation:
The student is asking about the average elevation of a town named Marlinton, given that Marlinton's average elevation is two and a half times that of Ava's town, which has an average elevation of -6.4 meters. To find Marlinton's average elevation, we simply need to multiply Ava's town elevation by 2.5.
Calculation:
Ava's town elevation = -6.4 meters
Marlinton's elevation = 2.5 × (Ava's town elevation)
Marlinton's elevation = 2.5 × (-6.4 meters)
Marlinton's elevation = -16 meters.
Therefore, the average elevation of Marlinton is -16 meters, which means it is 16 meters below sea level. Marlinton's elevation is also two and a half times deeper below sea level compared to Ava's town.
