the table below shows the relationship between the approximate number of hours and the corresponding number of hours and the corresponding number of days on Saturn.

Answer: There are 768 hours in 72 days.
Step-by-step explanation:
Given: The number of hours in 25 days = [tex]266\frac{2}{3}=\frac{800}{3}[/tex] hours
Let x be the number of hours in 72 days.
Since the relation between number of hours and days is directly proportional, thus
[tex]\frac{x}{72}=\frac{\frac{800}{3}}{25}\\\Rightarrow\ x=\frac{800\times72}{3\times25}\\\Rightarrow\ x=768\text{ hours}[/tex]
Hence, there are 768 hours in 72 days.
