A train 500m long takes 10 sec to cross a man walking at 5kmph in a direction opposite to that of the train. Find the speed of the train?	Choose the correct choice from the following options
A) 175kmph  B) 150kmph  C) 162kmph  D) 145kmph  E) 100kmph
Let the speed of the train be x kmph   Speed of the train relative to man = x+5 = (x+5)*5/18 m/sec   500/[(x+5)*5/18] = 10   10(x+5) = 1800   x = 175kmph   175kmphnswer is 175kmph
