Question

the temperature of a hot iron rod is 250 degree celsius .Every minute,the temperature drops down by 10 degree celsius. What will be the temperature of the iron rod after 12 minutes

Answer 1

If the temp of the rod decreases by 10 degree C every minute, we can assume that by 12 minutes, the temp of the rod will have decreased by 12 X 10 = 120 degree Celsius.
Then, we simply subtract 120 from 250, which gives us 130 degree C.

Hope this helps.
