Question

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 1

Answer: There are 768 hours in 72 days.

Step-by-step explanation:

Given: The number of hours in 25 days = $266\frac{2}{3}=\frac{800}{3}$ hours

Let x be the number of hours in 72 days.

Since the relation between number of hours and days is directly proportional, thus

$\frac{x}{72}=\frac{\frac{800}{3}}{25}\\\Rightarrow\ x=\frac{800\times72}{3\times25}\\\Rightarrow\ x=768\text{ hours}$

Hence, there are 768 hours in 72 days.
