Tammy and Jodi assembled 420 circuit boards in 8 hours. The next day they assembled 36 more circuit boards in the same amount of time. What was their average rate on the second day?

If they had completed 420 boards in eight hours that would be 52.5 boards every hour but if they only produced 36 in the eight hours a day schedule that they only completed 4.5 board every hour
