A model plane is 1/48 the size of the actual plane.if the model plane is 28 inches long how long it's the actual plane

Use a proportion. Cross multiply and solve for x.

1/48 = 28/x

x = 1,344 inches = 112 feet

I got 1344 inches and 112 feet.

To find the length of the actual plane, we need to determine the scale factor between the model plane and the actual plane. In this case, the scale factor is 1/48.

Given that the model plane is 28 inches long, we can use the scale factor to calculate the length of the actual plane by multiplying the length of the model plane by the reciprocal of the scale factor:

Actual plane length = (model plane length) * (1 / scale factor)

Actual plane length = 28 inches * (1 / 1/48)

Actual plane length = 28 inches * 48

Actual plane length = 1344 inches

Therefore, the actual plane is 1344 inches long.

To find out the length of the actual plane, we can set up a proportion using the given information:

Let's assume the length of the actual plane is "x inches."

The proportion can be set up as follows:

Model Plane Length / Actual Plane Length = Scale Factor (Model Plane size compared to Actual Plane size)

Substituting the values we have:

28 inches (Model Plane Length) / x inches (Actual Plane Length) = 1/48

Now, we can solve for x. To do this, we can cross-multiply and then solve for x:

28 * 48 = x

x = 1344

Therefore, the length of the actual plane is 1344 inches.
