Two runners A and B complete a 150 meters race in 24 seconds and 36 seconds respectively. By how many meters will A defeat B?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 50 meters
A finishes the race in 24 seconds. A beats B by the distance B still has to run at that moment.
\( \displaystyle \text{Speed of B} = \frac{150}{36} = \frac{25}{6} \text{ m/s} \)
\( \displaystyle \text{Distance run by B in 24 s} = \frac{25}{6} \times 24 = 100 \text{ m} \)
\(150 - 100 = 50 \text{ m}\)
So A defeats B by 50 meters.
