Length of Train, platform, cave which ever given.

Time taken to cross an object or platform or cave or tunnel

Then calculate the length, speed and apply the formula

**Given speed of the Train(m) = 3600 **

** Length of the Train(m) Time taken to cross (sec)**

fill the above equation with given data and solve to find answer.

** 40*1000 = 3600**

** 200 x**

=> (40*1000)***x** = 3,600*200 (cross-multiplied)

40,000**x** = 7,20,000

**4x** = 72

**x** = 72/4
