A 300 m long train crosses a platform in 48 sec while it crosses a signal pole in 18 sec. What is the length of the platform?
Choose the correct choice from the following choices
A) 500 B) 350 C) 828 D) 277 E) 122
Speed = 300/18 = 50/3 m/sec.   Let the length of the platform be x meters.   Then, (x + 300)/489 = 50/3   3x + 900 = 2400 =&gt; x = 500 m.   500nswer: 500
