A 300 meter long train crosses a platform in 30 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?

Answer/Solution

200m

Steps/Work

Speed = [300 / 18] m/sec = 50/3 m/sec.
Let the length of the platform be x meters.
Then, x + 300 / 30
= 50/3
3(x + 300)
= 1500 è x
= 200m.

Calculated Answer

200

Step by Step Solution

In order to solve problem, you must evaluate n₁ * n₀ / n₂ - n₀.

n₀ =	300
n₁ =	30
n₂ =	18

n₁ * n₀ / n₂ - n₀
Evaluate n₀ / n₂ = 16.666666666667
n₁ * 16.666666666667 - n₀
Evaluate n₁ * 16.666666666667 = 500
500 - n₀
Evaluate 500 - n₀ = 200
200
The answer to the problem and the result of n₁ * n₀ / n₂ - n₀ is 200
