Question 117440: A printer can print 1 page in 6 seconds. It shuts down for 2 minutes to cool off after every hour of operation. How many minutes will it take the printer to print 4500 pages?
Just checking is it 462?
600 pages in 1hr
4500 pages= 7.5 hours + ( 6hrs x 2 cooldown)=another 12 min = 462 min?

For printing 4500 pages it will take at 4500x6 sec = 450 mins. of printing = 7.5 hrs. of printing.
After every 1 hr. it shuts down for 2 mins. for cooling.
So, in the mean time there will be 7 shut down ocassions amounting to time = 7x2 = 14 minutes.
Hence, total time reqd is 450 + 14 = 464 minutes.
