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 runs 150 m in 24 s.
B runs 150 m in 36 s.
B’s speed:
$v_B = \frac{150}{36} = 4.166\ldots \text{ m/s}$
In 24 seconds, B covers:
$\text{distance} = v_B \times 24 = \frac{150}{36} \times 24 = 100$
A finishes 150 m in that time.
So A defeats B by:
$150 - 100 = 50$
Answer: 50 meters
