John can make burgers at the average speed of 10 seconds each. In a day, he works for 6 hours at McDonalds with a 5-minute break every hour. What is the maximum number of burgers he can make per day?
in this qestion i think the solution has error.
As john takes 5 minute break after every one hour  of work. so in this case he will take 5 minutes 5 breaks in between six hours.
