Answer:
22.5 minutes.
Step-by-step explanation:
Let x represent time spent by visitor at the tower.
We have been given that the Skylon tower in Niagara Falls Canada has a revolving restaurant 775 feet above the falls. The restaurant makes a complete revolution once every hour.
We know that 1 hour equals 60 minutes.
We also know that 1 full revolution equals 360 degrees.
Now, we will use proportions to solve our given problem as:
[tex]\frac{\text{Time}}{\text{Rotation}}=\frac{60\text{ min}}{360^{\circ}}[/tex]
[tex]\frac{x}{135^{\circ}}=\frac{60\text{ min}}{360^{\circ}}[/tex]
[tex]\frac{x}{135^{\circ}}*135^{\circ}=\frac{60\text{ min}}{360^{\circ}}*135^{\circ}[/tex]
[tex]x=\frac{1\text{ min}}{6}*135[/tex]
[tex]x=22.5\text{ min}[/tex]
Therefore, the visitor spent 22.5 minutes at the tower.
