Question

A reclying plant processes an average of 1/3 ton of glass each minute. at approximately what rate does the recycling plant process glass, in tons per day?

Answer 1

Answer: 480 tons per day .
___________________________________________________
(1/3) ton / 1 minute = __?__ ton/ day.

1 day = 24 hours ;

1 hour = 60 minutes;
______________________________________________
1 day = ? minutes?

1 day * (24 hr / 1 day) * (60 min. / 1 hr) = ? minutes ?_____________________________________________
The units of "day" and "hr" cancel out to "1",
and we are left with: (24 * 60) minutes = 1440 minutes;
__________________________________________________
1 day = 1440 minutes (exact value) ;
_______________________________

So, (1/3) ton / 1 minute = ? ton / day?

[ (1/3) ton / 1 min ] *(1440 min. / day) = [(1/3) * (1440)] tons / day =
________________________________________________________
= (1440 / 3 ) tons / day = 480 tons / day .
