A train 110 m long is running with a speed of 50 km/h. In how many seconds will the train pass a man who is running at 5 km/h in the direction opposite to that in which the train is going?
Choose the correct choice from the following options:	A) 6.1	B) 7.2	C) 8.3	D) 9.4	E) 10.5
The speed of the train relative to the man = 50 + 5= 
<gadget id="calculator">50 + 5</gadget>
<output>55</output>
55 km/h.   55000 m/h * 1h/3600 s= (550/36) m/s   (110 m) / (550/36 m/s) = (110 * 36) / 550 = 36/5= 
<gadget id="calculator">36/5</gadget>
<output>36/5 = around 7.2</output>
7.2 seconds   The answer is 7.2.
