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?

50 meters

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
