Answer:

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

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.

  • Where;

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

  • Thus, for every graph height of x the real height will be;

h = 3x/2

For a height of 10.2, we will have;

h = 3 × 10.2/2

h = 15.3 ft
