Answer:

The answer to your question is 20 in

Step-by-step explanation:

Data

ratio  1 : 30

real length = 55 ft

toy train length = ?

Process

1.- Use ratio and proportions to solve this problem.

                           1 : 30 :: x : 55

solve

                           x = (55 x 1) / 33

Simplification

                           x = 55/33

result

                           x = 1.67 ft

2.- Convert the length to in

                         1 ft ------------------ 12 in

                        1.67 ft --------------   x

                          x = (1.67 x 12) / 1

-Simplification

                          x = 20/1

-Result

                           x = 20 in
