In the mesosphere, the atmospheric layer between 50 km and 80 km in altitude, the average atmospheric temperature varies linearly with altitude. If the average temperature at 50 km altitude is 10°C and the average temperature at 80 km is -80°C, then at what altitude is the average temperature -50°C?
A. 60 km
B. 65 km
C. 70 km
D. 75 km
