Answer 1

Answer:

(i) 25 degree

(ii) 14 degree

Step-by-step explanation:

(i) 20 degree + 5 degree = 25 degree Celsius

(ii) 20 degree is subtracted by 0.5 degree every hour so if we keep subtracting 0.5 every hour so the final answer would be 6 degree. Can also do it in the following process:-

If every hour counts for -0.5 degree so every 2 hours will count for 1 -degree. So we would divide 12 by 2 so the answer will be 14.
