Expert Answer:

begin mathsize 16px style Current space temperature equals 40 degree straight C
Temperature space lowers space by space 5 degree straight C space every space hour.
Then comma space in space 10 space hours comma space temperature space lowered equals 5 cross times 10 equals 50 degree straight C
Therefore comma space temperature space after space 10 space hours equals 40 degree straight C minus 50 degree straight C equals negative 10 degree straight C end style
