Difficulty: Easy
Correct Answer: 32 8/11 min past 6
Explanation:
Introduction / Context:
Relative speed of minute vs. hour hand is 5.5 degrees per minute. For meeting (coincidence) after h o’clock, the standard result is t = (60/11)*h minutes past h o’clock.
Given Data / Assumptions:
Concept / Approach:
Formula for coincidence: t = (60/11) * h minutes.
Step-by-Step Solution:
t = (60/11) * 6 = 360/11 = 32 8/11 minutes.Hence, time = 6 : 32 8/11.
Verification / Alternative check:
Angle at 6 : t = |180 − 5.5 t| = 0 → t = 32 8/11 min satisfies.
Why Other Options Are Wrong:
Other fractions are typical distractors; they do not satisfy the coincidence condition.
Common Pitfalls:
Using 30/11 instead of 60/11; mixing “opposite” with “together.”
Final Answer:
32 8/11 min past 6
