Bridge Size
How do you scale down the Golden Gate bridge to size for a math project?
You use simple division.
The bridge is 1.7 miles long,
it is about 250 feet above the water
and the towers extend another 500 feet into the air.
You decide how big you want to make your model:
Let's say you want to make it 2 feet long.
Then you have a scale factor of 1.7 miles = 2 feet
1.7 * 5280 * 12 = 107712 inches (actual bridge)
24 inches (your model)
107712 / 24 = 4488 : 1
(or 1.7 * 5280/2 = 4488)
The distance between the towers (4200') would be .93 feet or 11.3 inches, about half the whole bridge.
Your towers would be 500 / 4488 feet = 0.111 feet above the bridge
or 1.3 inches.
and half of that below the bridge to the water.
