+328 The donut machine churns out 1 donut every 8 seconds. If there are 6 identical donut machines working at the same time, what is the speed of donut making in terms ofboxes per hour, where each box contains a dozen donuts?
+538 There are 60*60=3600 seconds in 1 hour. Every 8 seconds, 1 donut comes out. 3600/8 is 450. There are 6 machines working. 6*450 is 2700. One box is 12 donuts. 2700/12 is 225.
So the machines make enough donuts to fill 225 boxes per hour
