A train running at a speed of 36 km/h passes an electric pole in 14 seconds. In how many seconds will the whole train pass a 360-meter long platform?	Choose the most appropriate option:
A) 44
B) 46
C) 48
D) 50
E) 52
Let the length of the train be x meters.   When a train crosses an electric pole, the distance covered is its own length x.   speed = 36 km/h = 36000 m / 3600 s = 10 m/s   x = 14 * 10=

<output>140</output>
140 m.   The time taken to pass the platform= (140 +360)/ 10= 
<gadget id="calculator">(140 +360)/ 10</gadget>
<output>50</output>
50 seconds   The answer is 50.
