Answer:
14°C
Step-by-step explanation:
Place A = 2500 m = 20°C
Place B = 1500 m = ? °C
First of all, we know that the air temperature decreases with 6°C at every 1000 m.
So, now it is easy to find the temperature from place B.
If in place A, at 2500 m is 20°C, then at place B the temperature will be with 6°C lower.
Place B = 20°C - 6°C = 14°C
