In a kilometer race, \(A\) beats \(B\) by 50 meters or by 5 seconds, then the time taken by \(A\) to complete the race is
- A 85 seconds
- B 90 seconds
- C 95 seconds
- D 120 seconds
Answer & Solution
Correct Answer
(C) 95 seconds
Step-by-step Solution
Detailed explanation
Distance B covered when A finished: \(1000 \text{ m} - 50 \text{ m} = 950 \text{ m}\) B's speed: \(v_B = \frac{50 \text{ m}}{5 \text{ s}} = 10 \text{ m/s}\) Time taken by B to complete the race: \(t_B = \frac{1000 \text{ m}}{10 \text{ m/s}} = 100 \text{ s}\) Time taken by A to…
