Question

A toy train is built with the ratio of the model to the real of 1:30. If the real train is supposed to be 55 feet long, how many inches is the toy train?

Answer 1

The answer to your question is 20 in

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
