The internal angles of a triangle always add up to 180 degrees.
Carletta works at the rate
x = (1 board)/(12 hours) = 1/12 mb/hr
Johnathan works at the rate
y = (1 board)/(16 hours) = 1/16 mb/hr
The combined working rate is
1/12 + 1/16 = 7/48 = 0.1458 mb/hr
The time to build a mother board (mb) when working together is
(1 mb)/(0.1458 mb/hr) = 6.8587 hrs = 7 hours (nearest hour)
Answer: 7 hours
