Answer:

9 hours

Step-by-step explanation:

speed of cooling =3 degree per hour

Now it reduces 3 degrees in 1 hour then it will reduce 1 degree in ⅓hours

Starting temerature is 32 degree and it has to be reduced by 32-5=27 degrees

now 1 degree in ⅓hours then 27 degree in 27×⅓hours=9hours

yop29: 32,29,26,23,20,17,14,11,8,5,2,-1

yop29: every -3 degree is a change in temp.

yop29: by going through this, we get our ans as 9 hrs
