Question

For every 1000ft above sea level, the air temperature decreases by 4degrees. The highest natural point in Texas is Guadalupe Peak at 8751ft. If the temperature at sea level is 76degrees what is the temperature near the summit at 8000 ft?

Answer 1

the temperature near the summit is 44F

what is the temperature near the summit at 8000 ft?

We know that:

• The temperature at the sea level is 76F
• For every 1000ft above the sea level, the temperature decreases by 4F

Then we have the linear equation:

y = (-4F/1000ft)*x + 76F

Where x is the height above the sea level.

We want to get the temperature near the summit at 8000ft, so we just need to evaluate in x = 8000ft:

y =  (-4F/1000ft)*8000ft + 76F = 44F
