Question

An engine pulls four identical carriages. The engine is the length of 2/3rd the length a carriage and the total length of the train is 86.8 m. Find the length of the engine.​

Answer 1

Answer:

I assume you meant that the total length of the train is 86.8m.

Let ’n’ be the length of a carriage.

Then the length of the engine is (2/3)n.

4n+(2/3)n = 86.8

(14/3)n = 86.8

n =18.6. (2/3)n = 12.4.

Each carriage is 18.6 meters long.

The engine is 12.4 meters long.
