There is a 2 hour gap in between 8:30 and 10:30 and since they only made 600 jars throughout those 2 hrs you can divide 600 by 2 so you can fins out how many jars they make every hr.
Or you can multiply 600 and 2 to find out how much they make within the next 2 hrs.
There are two hours between 8:30 A.M. and 10:30 A.M. If they make 600 jars of peanut butter per two hours, then they will make 300 jars per hour. 1800 divided by 6 is 300, so they need six hours to make 1800 jars of peanut butter. So, if they begin production at 8:30 A.M., the factory will have produced 1800 at 4:30 P.M.
So we have 10 painters and sculptors all together. There are also 22 people in total. That means we have a 10/22 chance it will be one of those artists. This fraction can be reduced to 5/11.
