70
A train 125m long takes 6 sec to cross a man walking at 5kmph in a direction opposite to that of the train. Find the speed of the train?
{ "A": "65 kmph", "B": "70 kmph", "C": "75 kmph", "D": "80 kmph", "E": "85 kmph" }
subtract(divide(divide(125, 6), const_0_2778), 5)
divide(n0,n1)|divide(#0,const_0_2778)|subtract(#1,n2)|
"let the speed of the train be x kmph speed of the train relative to man = x + 5 = ( x + 5 ) * 5 / 18 m / sec 125 / [ ( x + 5 ) * 5 / 18 ] = 6 30 ( x + 5 ) = 2250 x = 70 kmph answer is b"
