one rope will take 60 minuit...You have two ropes. <br /><br />one rope will take 60 minuites to burn completely.<br /><br />light the first rope from two ends .<br />light the second rope from only one end.<br /><br />after 30 minuites , the first rope will burn completely and second rope will burn half(so it can still burn for another 30 minuites).<br /><br />Now light the second rope on the second end. In 15 minuites , the second rope will completely burn.<br /><br />so the total time is 30+15 = 45 minuites.<br /><br />-Sriram Thallamsriramhttps://www.blogger.com/profile/12268823840437554381noreply@blogger.com
