Question

A student builds a model of her bedroom. The scale is 1:25. In the scale model, the students bed is 3 inches long. How long is the students actual bed?

Answer 1

The student’s actual bed is 75 inches long

Step-by-step explanation:

Here in this question, we want to find out the length of the student’s actual bed.

The ratio of the model to the real is 1:25

Let the actual length of the bed be x inches

Thus;

1/25 = 3/x

By cross multiplying

1 * x = 3 * 25

x = 75 inches
