Here's your answer

The temperature decreases at a rate of 2degrees per hour

It was actually 12 degree above zero

We need to find at what time does the the temperature drops down to 10 degree below zero that is -10

Temperature change = 12-(-10)

=12+10

=22

For one hour it drops by 2degree

So it takes 22/2=11hours to attain -10 degree

It means, at 11'o clock e temperature falls down to -10 degree
