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
Throughout this, I'm assuming that the scale is: 1 square = 1
Not 100% sure if my answers are correct.
