Answer:
26.67 hours
Step-by-step explanation:
Given:
Number of hours of service projects (N) = 40 hours
Time taken to complete the garden project is two-third of the total time.
Therefore, the time taken to complete the garden project can be obtained by multiplying the part to the total time taken.
So, the hours taken for garden project is given as:
[tex]x=\frac{2}{3}\times N\\\\x=\frac{2}{3}\times 40\\\\x=\frac{80}{3}\\\\x=26.67\ hours[/tex]
Therefore, it took 26.67 hours to complete the garden project.
