Analog Clock and Minute Marks Puzzle

Click For Summary

Discussion Overview

The discussion revolves around a puzzle involving the positions of the minute and hour hands on a 12-hour analog clock. Participants explore the implications of the minute hand being on a minute mark and the hour hand being two minute marks behind it, seeking to determine the exact time.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant calculates that the angle between the minute and hour hands is 15 degrees, leading to a proposed time of 4:24.
  • Another participant expresses confusion about the conclusion, questioning whether other times could also satisfy the conditions of the puzzle.
  • A request for clarification on the reasoning behind the proposed time is made, indicating a desire for further explanation.

Areas of Agreement / Disagreement

There is no consensus on the solution, as one participant proposes a specific time while another questions the validity of that conclusion, suggesting that multiple interpretations may exist.

Contextual Notes

The discussion does not resolve the mathematical steps or assumptions involved in determining the time, leaving the reasoning behind the proposed solution open to interpretation.

The minute hand of a 12 hour analog clock is situated precisely on a minute mark, while the hour hand is situated exactly 2 minute marks behind the minute hand.

What time is it?

Note: For purposes of the problem, each hour mark is deemed as a valid minute mark.

4:24
:smile:
 
Well, just rambling here. Each minute mark is 7.5 degrees. So there will be 15 degrees between the two hands. And in conclusion, it will be 4:24
 
Ah beat me to it
 
For the record, how did you do it?
 
i don't get it, why 4.24 could it not be other numbers?
