Question

The temperature was very cold then it dropped 10 degrees and then it increased 40 degrees the temperature is now 16 degrees. What is the starting temperature?

Answer 1

-14 degrees

Explanation:

In this question, we are asked to calculate the starting temperature if we know what the temperature is now and the kind of temperature change that has happened.

Now, since we do not know the initial temperature , let’s call it x

from the question, it dropped by 10 and increased by 40 and finally with a temperature of 16.

mathematically

x-10+40= 16

x+30 = 16

x = 16-30

x = -14

Answer 2

The initial temperature was To = -14 degrees

Explanation:

Solution:-

- We will take the starting temperature to be = Ti

- The final temperature, Tc = 16 degrees

- We are given that there is a drop of 10 degrees from initial temperature To. We can mathematically express this as:

To - 10

- Then there is a rise of 40 degrees after the drop of 10 degrees. The mathematical expression would be:

To - 10 + 40

- The current temperature is Tc. We can equate the expression developed to final temperature:

To - 10 + 40 = Tc

- Solve for To:

To = 16 - 40 + 10

To = -14 degrees
