Question

For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric temperature can be described by the formula t = −0.0035a + g, in which t is the atmospheric temperature in degrees Fahrenheit, a is the altitude, in feet, at which the atmospheric temperature is measured, and g is the ground temperature in degrees Fahrenheit. Solve the equation for a. If the atmospheric temperature is −38.8 °

F and the ground temperature is 20 °
F, what is the altitude?

Answer 1

A = 16,800 feet

Explanation:

a = (t-g)/- 0.0035

- 38.8 = - 0.0035a + 20

a = (-38.8 - 20) / -0.0035

a = ( - 58.8) / - 0.0035

a = 16,800 feet
