A scale model of the Golden Gate Bridge in San Francisco has a main span that is 284 centimeters long. If the scale of the model is 1 cm : 15 ft, how long is the main span of the bridge?
3,150 ft
2,130 ft
19 ft
4,260 ft
please help I think the answer is b
1cm : 15ft = 284cm : 15*284 ft
so, (b) is not it
your answer is d 4,260
L = 284cm * 15ft/cm =
To find the length of the main span of the bridge, we can use the given scale and the length of the model. The scale states that 1 centimeter on the model represents 15 feet in reality.
To find the actual length of the main span, we need to convert the length of the model in centimeters to feet using the scale.
So, if the model has a main span of 284 centimeters, we can calculate the actual length of the main span of the bridge by multiplying 284 by the conversion factor:
284 centimeters * (15 feet/1 centimeter) = 4,260 feet
Therefore, the correct answer is d) 4,260 ft.
