Question

4.
The temperature at 7 A.M was 8°C below zero. If it increases at the rate of 2°C per
hour at what time would the temperature be 10°C above zero
​

Answer 1

Answer:

4PM

Step-by-step explanation:

We can see that total change has been increased by 18⁰C

And it changes at rate of 2⁰C per hour

So, basically it would take 18/2= 9 hours

So, from 7AM in the morning, after 9 hours,

it would be 4PM

(7+9=16)

16=4PM
