2:30 thermometer read 44 degrees Celsius. It risen 3 degrees between noon and 2:30 pm and 12 degrees between 7 am and noon. What was the temp at 7 am
work backwards,
2:30 pm ---- 44°
noon -------- 41°
7:00 am ----- 29°
To find the temperature at 7 am, we need to subtract the temperature rise between 7 am and noon from the temperature at noon.
First, let's calculate the temperature rise between 7 am and noon. We know that the temperature rose 12 degrees between 7 am and noon. So, at noon, the temperature must have been 44 degrees Celsius - 12 degrees Celsius = 32 degrees Celsius.
Now, we can find the temperature at 7 am. Since the temperature rose 3 degrees between noon and 2:30 pm, we need to subtract this rise from the temperature at 2:30 pm. The temperature at 2:30 pm is given as 44 degrees Celsius. Thus, the temperature at 7 am would be 44 degrees Celsius - 3 degrees Celsius = 41 degrees Celsius.
Therefore, the temperature at 7 am was 41 degrees Celsius.
