Solve the following word problem. The air temperature at 9 a.m. is −5.8 degrees Celsius. The air temperature at noon is −1.6 degrees Celsius. What is the change in the temperature during these three hours? Write and solve an equation to show your answer. Then explain what your answer mean

Answer 1

To find the change in temperature during these three hours, we need to subtract the air temperature at 9 a.m. from the air temperature at noon.

Change in Temperature = Temperature at Noon - Temperature at 9 a.m.

Change in Temperature = (-1.6 degrees C) - (-5.8 degrees C)

To subtract a negative number, we can rewrite this equation as:

Change in Temperature = -1.6 degrees C + 5.8 degrees C

Change in Temperature = 4.2 degrees Celsius.

Therefore, the change in temperature during these three hours is 4.2 degrees Celsius, showing that the temperature increased by 4.2 degrees.
