A 300 m long train crosses a platform in 33 sec while it crosses a signal pole in 18 sec. What is the length of the platform?	Pick one:  A) 288  B) 350  C) 889  D) 276  E) 250
Speed = 300/18 = 50/3 m/sec.   Let the length of the platform be x meters.   Then, (x + 300)/33 = 50/3   3x + 900 = 1650 =&gt; x = 250 m.   Answer:250
