Frank and his mom are planting vegetables in their garden. Frank has finished planting 8 rows of carrots so far and is planting new rows at a rate of 1 row per hour. His mom has finished 2 rows of tomatoes and will continue planting at 3 rows per hour. Once the pair get to the point where they have finished the same number of rows, they will take a break and decide what to plant next. How long will that take? How many rows will they each have completed?
