That will take half the time (1h) to burn a coil.<br />~ Most of you should be able to get this!~<br /></span><span style="color:#3333ff;"></span><br />(B) How to measure exactly 15 min using two coils?<br /><br /><span style="color:#ffff66;">For coil 1, burn from both ends. At the same time, lit one end of coil 2.<br />When coil 1 completes burning, coil 2 would have been burnt halfway only. At that moment, lit the other end of coil 2.<br />Can you figure out why?</span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8618538797178841235-3256705257311090745?l=mathbeyondclassroom.blogspot.com' alt='' /></div>M.P.http://www.blogger.com/profile/15931410112482567049noreply@blogger.com0tag:blogger.com,1999:blog-8618538797178841235.post-1450252512439612862009-07-28T19:07:00.001-07:002009-07-28T20:26:19.152-07:00Few months ago, my brother came home with a puzzle from his NDU camp that made everyone in the family cracked our head.<br /><br />It is something made up over mosquito coils.
