<gadget id="calculator">0.75*72</gadget>
<output>54</output>
54   Time taken by blue lizard to cover half dist=27   As green lizard started early it will reach   36-5.5= 
<gadget id="calculator">  36-5.5</gadget>
<output>30.5</output>
30.5   So, extra time taken by green lizard is  36.5-30.5= 
<gadget id="calculator"> 36.5-30.5</gadget>
<output>6</output>
