Difficulty: Easy
Correct Answer: 4.14 Km/h
Explanation:
Introduction / Context:
This is the same structure as a prior item; we recompute to confirm consistency.
Given Data / Assumptions:
A’s speed = 5 km/h = 1.3889 m/s; B runs 92 m; B finishes 8 s after A.
Concept / Approach:
Compute A’s finish time for 100 m, then add 8 s for B’s finish time over 92 m.
Step-by-Step Solution:
Verification / Alternative check:
Matches earlier derived value.
Why Other Options Are Wrong:
Numbers that do not match the precise timing.
Common Pitfalls:
Mixing metres and kilometres without consistent conversions.
Final Answer:
