Jake's family is moving to a new home. they packed 22 boxes in 1 5/6 hours. what is the average number of boxes they packed per hour?

It would be an average of 12 boxes per hour, because if there were only 11 boxes per hour, and there is not another full hour to make it two hours, the box would not be fully packed. Therefore, it has to be an average of 12 boxes per hour to get all 22 boxes fully packed.

I hope this helps you, even though it has been about a day since you posted it.

There is 240 red cars and there is 400 blue cars because 240/3=80 and 80*5=400
