Question

Between 6am and 10am the temperature rose by 5 degrees F. Between 10am and 2pm the temperature rose by 6 degrees F. Between 2pm and 6pm the temperature rose by 0 degrees C. Would you be able to tell how much the temperature rose since 6am? Why or why not?

Answer 1

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°.

⇒ We would be able to tell how much the temperature rose since 6am.

Because we have given adequate informations.

Answer 2

No, a degree in C is much larger than a degree in F, so since the two are used in this question, it is imposable to know if the temperature raised at all between the time of 2 pm and 6pm
