Answer 2

Answer: 6 hours

given,

change in temperature in one hour= -4 degrees celsius.

to find,

the number of hours it will take for the change in temperature to be -24 degrees celsius.

solution,

Let the number of hours be X.

we know that the temperature changes at a rate of -4 degrees celsius per hour and the overall change is -24 degrees celsius.

change in temperature in one hour × total number of hours = total temperature change.

according to the question,

-4 × X = -24

X = -24 ÷ (-4)

X = 6 hours.

therefore, it will take 6 hours for the change in temperature to be -24 degrees celsius.
