Answer:
- equation: 1/t = 1/8 + 1/6
- time: 3.43 hours
Explanation:
1) Working speed of Cody: 1 project / 8 hours
2) Working speed of Kaitlyn: 1 project / 6 hours
3) Joint working speed = working speed of Cody + working speed of Kaitlyn
⇒ 1 project / t = 1 project / 8 hours + 1 project / 6 hours
1 / t = 1 / 8 + 1 / 6
That is the equation to solve.
4) Solution of the equation.
1/t = [3 + 4] / 24
1/t = 7/24
⇒ t = 24/7 ≈ 3.43 hours
