Calculate: 1 year __?__How many minutes?_______?
1 year = 365 days;
1 day = 24 hours;
60 minutes = 1 hour.
________________________________
So: To calculate many minutes in 1 yr.
_______________________________________
1 yr * (365 d/ yr) * (24 h /d) * (60 min/ h) = (365)*(24)*(60) min. ;
______________________________________________________
1 year = (365)*(24)*(60) min. = 525,600 min.
_____________________________________________
(3.5 million deaths / 1yr) * (1yr / 525,600 min) =
(3.5 million deaths / 525,600 minutes) =
(3.5 million) / (525,600) deaths per minute;
Note: "3.5 million = 3,500,000" ;
3,500,000 / 525,600 = 6.6590563165905632
→ round to "6.7" ;
→ {use 2 (TWO) significant figures};
