What is the length of the plaƞorm.
Choose the correct answer
A) 310 meter  B) 335 meter  C) 345 meter  D) 350 meter  E) None of these
Explanation:   Speed = 350 meteristance/Ɵme = 300/18 = 50/3 m/sec   Let the length of the plaƞorm be x meters   then   350 meteristance=Speed   ∗   Timex+300=503   ∗   39=&gt;3(x+300)=1950=&gt;x=350 meters   Answer: 350 meter
