Solution

✅ Correct Option: 3
  • Race distance = 700700 m
    • Amit's time = 2020 seconds
    • Rahul's time = 2525 seconds

Amit's speed =700 m20 s=35 m/s= \frac{700 \text{ m}}{20 \text{ s}} = 35 \text{ m/s}

Rahul's speed =700 m25 s=28 m/s= \frac{700 \text{ m}}{25 \text{ s}} = 28 \text{ m/s}

When Amit reaches the finish line (after 20 seconds), Rahul has only covered a portion of the race.

To find this distance, multiply Rahul's speed by the time Amit took to finish:

Rahul's distance after 20 seconds =28 m/s×20 s=560 m= 28 \text{ m/s} \times 20 \text{ s} = 560 \text{ m}

Distance difference =700 m−560 m=140 m= 700 \text{ m} - 560 \text{ m} = 140 \text{ m}
