Final answer:
The correct answer is option (B). At an altitude of 2,000 feet, the likely temperature will be 62 degrees Fahrenheit, given that the temperature rises by 0.1 degree Fahrenheit for every 100-foot increase in elevation from a base of 60 degrees at sea level.
Step-by-step explanation:
As the ground temperature at sea level is given as 60 degrees Fahrenheit, and there is an increase of 1/10 of a degree for every 100-foot elevation gain, we can use this information to estimate the temperature at an altitude of 2,000 feet.
For every 100 feet, the temperature increases by 1/10 of a degree. So, for 2,000 feet, we have 20 increments of 1/10 of a degree.
To calculate the temperature at 2,000 feet, we add this increase to the initial temperature:
[ 60 + 20 times frac{1}{10} ]
Simplifying this expression gives us the temperature at 2,000 feet.
[ 60 + 2 = 62 ]
Therefore, the likely temperature at an altitude of 2,000 feet is 62 degrees Fahrenheit.
So, the correct answer is:B) 62 degrees
This calculation assumes a linear relationship between elevation and temperature, and it's important to note that real-world atmospheric conditions can introduce variations to this simplified model.
