The temperature at the foot of a mountain is $+$ 8°C. It fell down by 10°C at the top of the mountain. The temperature recorded at the top is?
Given :
The temperature at the foot of a mountain is $+$ 8°C.
Fall down in the temperature at the top of the mountain is 10°C.
To do :
We have to find the temperature at the top of the mountain.
Solution :
$+8°C-10°C = -2°C$.
Therefore, the recorded temperature at the top of the mountain is $-2°C$.
