In ten minutes, Jordan can write out three Christmas cards.

In ten minutes, Jordan can write out three Christmas cards. Sierra can write out thirteen Christmas cards in the same amount of time. If they work together, how long will it take them to write out 144 Christmas cards?

My answer was 90 minutes. I would like to know if this is right?
