Question

texaschic101 · Answer

2.2 days is how many hrs ? That is where I am stuck.
It is a little over 48 hrs.... or 1 hr = .04166 rounds to .0417 days

I am trying to make a proportion..
26.4/2.2 = x/.0417 

I am not even sure if I set this up right.....you will need someone who knows more about what they are doing then me...sorry

texaschic101 · Answer

or do you just divide ??

johnweldon1993 · Answer

Well if we are breaking 1 day into a fraction...lets do 24 hours / 5 = 4.8 hours

That's 20% of 1 day...

So in 2 days there are 48 + 4.8 = 52.8 hours....

So I would just do

$$\large \frac{26.4}{52.8} = \frac{x}{1}$$

$$\large x = \frac{26.4}{52.8}$$

Sorry...up there I meant *in 2.2 days there are 48 + 4.8 = 52.8 hours

oh...you changed your days to  hrs instead of the way I set it up. Your way makes more sense...lol

So per hour what would that be

johnweldon1993 · Answer

Well when you solve that for 'x' what do you get?

alina123 · Answer

Oh never mind I read the proportion

texaschic101 · Answer

just do the division..
26.4 / 52.8

alina123 · Answer

Ok 0.5 rounded

johnweldon1993 · Answer

Right...

So that equates to .5 degrees Celsius an hour

That would mean .5 * 52.8 would be the 26.4

And that checks out
