Question

the initial temperature of an object is 15 degree Celsius and it is decreasing 4 degree Celsius per minute .find its temperature after 10 minutes. ​

Answer 1

Answer: -25 degree celsius

Step-by-step explanation:

Since the temperature is decreasing at the rate of 4 degree per min so after 10 mins the temperature will fall down by 40 degree Celsius.

So 15-40= -25 degree Celsius

Answer 2

Answer:

4×10=40degrees

Step-by-step explanation:

so we know in 10 mins the objects temperature decreases by 40 degrees but it has some temperature to it even before the temperature started cooling down that is 15 degrees

so temperature of that object after 10 mins is 15-40=-25degrees
