Speed of train relative to man =65+7= 
<gadget id="calculator">65+7</gadget>
<output>72</output>
72 km/hr.= 72 * 5/18= 
<gadget id="calculator">72 * 5/18</gadget>
<output>20</output>
20 m/sec.   Time taken to pass the men= 110 * 1/20= 
<gadget id="calculator">110 * 1/20</gadget>
<output>11/2 = around 5.5</output>
