Answer:

The length of the full-size train is 140 meters.

Explanation:

To determine the length of the full-size train, we will use the given relationship between the train at the amusement park and the full-size train.

From the question,

0.15 meter on the train at the amusement park represents 1 meter on the full-size train,

Let the length of the full-size train be x

Now,

If 0.15 meter on the train at the amusement park represents 1 meter on the full-size train

Then, 21 meters on the train at the amusement park will represent x meters on the full-size train

0.15 × x = 21 × 1

0.15x = 21

x = 21/0.15

x = 140 meters

Hence, the length of the full-size train is 140 meters.
