I have a question? e2e = 51.89 (Page 22).

[tom234]

Hi,
I was going through the D233 NASA paper.
I got the first part of page 22 first two answers...but the 3rd number still doesn't make sense to me.
I get that e2e=51.89 the closest I got was 56.421.
The great thing about solving on HP Prime is that equations have nice neat solutions...

Is there anyone that can find the correct answer as being e2e=51.89.
I will leave a video that was watched and the paper.

If you get the time and maybe you can explain to me how they got that answer.

Thank You.
