A) 19 sec B) 38 sec C) 36 sec D) 16 sec E) 11 sec
Speed of train relative to jogger = 45 - 9= 
<gadget id="calculator">45 - 9</gadget>
<output>36</output>
36 km/hr.= 36 * 5/18= 
<gadget id="calculator">36 * 5/18</gadget>
<output>10</output>
10 m/sec.   Distance to be covered= 240 + 140 = 360 m.   Time taken = 380/10= 
<gadget id="calculator">380/10</gadget>
<output>38</output>
