If the O scale (model train question) is 1/48 the acutal length. An O-scale locomotive is 1.05ft long. How long is the actual locomotive?
1/48 = 1.05/x
Cross multiply and solve for x.
x = 50.4 feet
To determine the actual length of the locomotive, we can use the scale ratio provided.
The O scale ratio is given as 1/48, which means that 1 unit in the model represents 48 units in reality.
In this case, we know that the O-scale locomotive is 1.05ft long in the model scale.
To find the actual length, we can set up a proportion:
1 unit (actual) / 48 units (model) = x units (actual) / 1.05 ft (model)
Cross-multiplying, we get:
1.05 ft (model) * 1 unit (actual) = 48 units (model) * x units (actual)
1.05 * x = 48
Dividing both sides by 1.05, we find:
x = 48 / 1.05
x = 45.71 ft
Therefore, the actual length of the O-scale locomotive is approximately 45.71 feet.
To find the length of the actual locomotive, we need to scale up the length of the O-scale locomotive using the scale factor.
The given scale is 1/48, which means that 1 unit in the O-scale is equal to 48 units in the actual size. Since the length of the O-scale locomotive is 1.05 feet, we can set up the following proportion:
1.05 feet (O-scale) / 1 unit (O-scale) = x feet (actual size) / 48 units (actual size)
To solve for x, we can cross multiply:
1.05 feet * 48 units = x feet
x = 50.4 feet
Therefore, the actual length of the locomotive is 50.4 feet.
