Answer:
Given,
Between 6am and 10am the temperature rose by 5 degrees F,
So, the total changes in temperature between 6 AM and 10 AM = +5°
And, Between 10am and 2pm the temperature rose by 6 degrees F
⇒ The total changes in temperature between 10am and 2pm = + 6° F,
Also, Between 2pm and 6pm the temperature rose by 0 degrees C,
⇒ The total changes in temperature between 2pm and 6pm = +0°,
Hence, the total changes in temperature since 6 AM = the total changes between 6 AM and 10 AM + The total changes between 10am and 2pm + The total changes between 2pm and 6pm
= 5° + 6° + 0
= 11°
Hence, the + sign shows the rise in temperature,
And, it is rose by 11°.
