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 means.
To find the change in temperature, we subtract the initial temperature from the final temperature.
Change in temperature = Final temperature - Initial temperature
Therefore, the change in temperature is (-1.6) - (-5.8) = 4.2 degrees Celsius.
The answer means that the temperature increased by 4.2 degrees Celsius during the three hours between 9 a.m. and noon.
Can you simplify
To find the change in temperature during the three hours from 9 a.m. to noon, we can subtract the initial temperature from the final temperature.
The initial temperature at 9 a.m. is -5.8 degrees Celsius.
The final temperature at noon is -1.6 degrees Celsius.
To find the change in temperature, we subtract the initial temperature from the final temperature:
Change in temperature = Final temperature - Initial temperature
Let's substitute the given values into the equation:
Change in temperature = (-1.6) - (-5.8)
Now, we need to simplify the equation:
Change in temperature = -1.6 + 5.8
By adding -1.6 and 5.8, we get:
Change in temperature = 4.2
The change in temperature during these three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
To find the change in temperature during the three hours, we need to subtract the initial temperature from the final temperature.
First, let's assign variables for the temperatures:
Initial temperature at 9 a.m. = T1 = -5.8 degrees Celsius
Final temperature at noon = T2 = -1.6 degrees Celsius
Now, we can write the equation to show the change in temperature:
Change in temperature = T2 - T1
Substituting the values:
Change in temperature = (-1.6) - (-5.8)
To subtract a negative number, we can rewrite the equation as:
Change in temperature = (-1.6) + 5.8
Now we can add these two numbers:
Change in temperature = 4.2 degrees Celsius
Therefore, the change in temperature during the three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
