Question

A scale of the Golden Gate Bridge in San Francisco Bay has

a main span that is 20 inches long. If the main span of the

bridge is 4200 feet long, what is the scale of the model?


Answer: 2520ft

Answer 1

2520ft

Explanation:

Calculation for what is the scale of the model?

Let x will be the span length

Hence,

x= 4200 feet long/20 inches long

x=210

Thus:

1 inch = 210 ft

1 ft = 2520

=2520ft

Therefore the scale of the model will be 2520ft
