Difficulty: Easy
Correct Answer: 10 seconds
Explanation:
Introduction / Context:
For striking clocks, the count of intervals equals (strikes − 1). Time scales with intervals if the interval length is constant.
Given Data / Assumptions:
Concept / Approach:
Interval = 22/11 = 2 s. For 6 strikes → 5 intervals.
Step-by-Step Solution:
Time = 5 * 2 = 10 seconds.
Verification / Alternative check:
Proportional reasoning is straightforward.
Why Other Options Are Wrong:
12 s and 14 s assume wrong interval counts; 9 s ignores uniformity.
Common Pitfalls:
Using 6 instead of 5 intervals for 6 strikes.
Final Answer:
10 seconds
