Jalen has a scale model of a train. 2 centimeters in the model represents 3 feet in a real train.

The height of the model train is 10.2 centimeters.

What is the height of the real train?

The height of the real train when the graph model is 10.2 cm is; 15.3 ft

We are given;

Scale of the model; 2cm to represent 3 feet in a real train.

2 cm is the graph height while 3 ft is the real height.

h = 3x/2

For a height of 10.2, we will have;

h = 3 × 10.2/2

h = 15.3 ft

15.3feet

Step-by-step explanation:

Given the scale model of a train as;

2cm = 3feet

We are to find the height of real train of height 10.2cm, we can write;

10.2cm = x

Divide both expressions

2/10.2 = 3/x

2x = 3×10.2

2x = 30.6

x= 15.3

Hence the height if the real train is 15.3feet

your answer is the frist one
