In a 200 m race, Rohan completes the race in 8 seconds and Vivan completes the race in 10 seconds. By how much distance Rohan beats Vivan?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 40 m
Rohan wins by the distance Vivan still has to run when Rohan finishes, that is, after 8 seconds.
\( \displaystyle \text{Vivan's speed} = \frac{200}{10} = 20 \text{ m/s} \)
\(\text{Distance Vivan runs in 8 s} = 20 \times 8 = 160 \text{ m}\)
\(\text{Rohan beats Vivan by } 200 - 160 = 40 \text{ m}\)
