A train 150 m long is running at 72 km/h. How long does it take to cross a platform 250 m long?

Question

Arvind went from point A to B and Surubhi from B to A. They met somewhere between continuing their journey. Arvind took 6 hours and Surubhi took 24 hours to reach the respective destinations after meeting. If Aravind traveled 54 Kmph, what is the distance AB.

Answer 1

Step 1: Speed \(= 72\times\dfrac{5}{18} = 20\) m/s.
Step 2: Total distance to cross \(= 150+250 = 400\) m.
Step 3: Time \(= \dfrac{400}{20} = 20\) s.

Quick Tip: To cross a platform, distance = train length + platform length.
