Multiple choice

A 150 metre long train was running at the speed of 36 km./hr. It takes 30 seconds to cross a platform completely. Find the length of the platform. 150 मीटर लम्बी रेलगाड़ी 36 किमी./घं. की चाल से चलते हुए एक प्लेटफार्म को 30 सेकेण्ड में पार करती है। प्लेटफार्म की लम्बाई ज्ञात करे।

  1. 300 meter 300 मीटर

  2. 160 meter 160 मीटर

  3. 100 meter 100 मीटर

  4. 150 meter 150 मीटर

  5. None of these इनमें से कोई नहीं

D Correct answer
Explanation

Speed = 36 km/hr = 10 m/s. Distance covered in 30 seconds = 10 × 30 = 300 m. This distance equals train length + platform length. So platform length = 300 - 150 = 150 m. The train must completely clear the platform, so the distance is sum of both lengths.
