An engine pulls four identical carriages. The engine is 2/3 the length of a carriage and the total length of the train is 86.8m. Find the length of the engine.
- A. 12.4m
- B. 12.4m
- C. 12.4m
- D. 12.4m
Answer: Option A
Explanation:
Let the length carriage=x
So the length of engine=(⅔)*X
According to question,
4x+(⅔)x=86.8
We get, x=8.266
So the length of engine = (⅔)*8.266=12.4
