To find the combined rate of Maria and Felipe, we add their individual rates.
Maria's rate is 1/8 orders per hour (since she can fill the order in 8 hours).
Felipe's rate is 1/9 orders per hour (since he can fill the order in 9 hours).
Together, their combined rate is 1/8 + 1/9 = 17/72 orders per hour.
To find out how long it will take them to fill the order together, we can divide 1 by the combined rate:
1 / (17/72) = 72/17 ≈ 4.24 hours
Therefore, it will take them approximately 4.24 hours to fill the order together.
