Guest Posted February 22, 2008 Report Share Posted February 22, 2008 Lets say that on a clock, y is the distance from the 12:00 to the minute hand (clockwise) and z is the distance from 12:00 to the hour hand. What time between 3-4 is y two times as much as z? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted February 23, 2008 Report Share Posted February 23, 2008 Say the minute hand (Y) and the hour hand (Z) are both on 12:00. That would make Y=0 and Z=0, leaving the second hand to pass between 3 and 4 (it's not specified that the minute hand or the hour hand, themselves, had to be between 3 and 4). If Y=0 and Z=0, then 2(Y) also = 0, so 2(Y)=Z. I guess that's kinda cheating, but it's all I got. Quote Link to comment Share on other sites More sharing options...

The time has to be between 3:00 and 4:00 Spoiler for hint: it is around 3:30 Edited February 23, 2008 by HRAEDIUS Quote Link to comment Share on other sites More sharing options...
0 Guest Posted February 23, 2008 Report Share Posted February 23, 2008 About 3:34 2z=y z-15=60/y solving for y from the two equations, y=33.6 (34 rounding to the nearest integer) Quote Link to comment Share on other sites More sharing options...

0 Guest Posted February 24, 2008 Report Share Posted February 24, 2008 I know where I made a mistake. 3:36 2z=y (z-15)/5=y/60 solving for y from the two equations, y=36 and z=18 Hope this one makes sense. Quote Link to comment Share on other sites More sharing options...

Lets say that on a clock, y is the distance from the 12:00 to the minute hand (clockwise) and z is the distance from 12:00 to the hour hand. What time between 3-4 is y two times as much as z?
