Help by telling you the answer? What have you done on this yourself?

1) What level of study are you at? (This will help the community identify what is likely the desired answer)

2) Were you given any other information in this problem?

The reason I ask is that, if one assumes that temperature change in this problem is linear, then the problem is straightforward. If you've learned calculus, this changes things.

I am new to this website. I apologize for not showing my work. I have worked on it a lot actually I just don't know if I'm right or not.

I tried...

2 hr/ 18 degrees x 10 degrees = degrees cancel so 1.11 hour

I tried also with the Newtons law of heating and cooling equation: but not sure if the K value I come up with using t= 2 hours and the temp difference 40 to 58 it the one I should use to find the time when the temp changes 10 more degrees.

Newton's law of heating and cooling applies here. Please show us exactly what you did.
