The Gateway Arch in St. Louis is 630 feet tall (or 192 meters), while the Palais Royale in Mumbai is 1,050 feet tall
(or 320 meters).
How much farther can a person at the top of Palais Royale see than a person at the top of the Gateway Arch?
You may use 4,000 miles as the radius of the Earth.
Here are some photos that I took when I visited the Gateway Arch last Fall:
View from the top of the arch (you can see the shadow of the arch in the picture)
View of the Mississippi River from the top of the arch
Inside the Keystone at the top of the arch
A sign in the cafeteria, but your answer must be more precise!
