Question 1
1.77843714 × 1014 (please note the raising of 14, not sure how to do subscript) divided by 15 thousand million commands per sec.
I worked this out as:
177 843 714 000 000 divided by 15 000 000 000 = 11 856.2476 secs
Before carrying on ... My concerns
a) Have I converted 1.77843714 × 1014 to the correct long form of 177 843 714 000 000? Yes
b) Have I added the correct number of 0's for 15 thousand million ( 15 000 000 000 )?Yes
OK
Now for converting to Hours, minutes, seconds....
11 856.2476 secs in hours =(11 856.2476 / 60) / 60 = 3.29340211 hours
My concerns
Have I used the right calculation for changing into hours and I am guessing that the number after the decimal is a deciamal of the hours (or fraction of the hours?) Yes so I would have to take the .29340211 and do the following..........
(60 / 100) * 0.29340211 = 0.176041266 No
So I now have 3 hours and 176041266 minutes (Am I correct)
Now ater this (If I am thinking along the right lines, how would I get the minutes??)
