A can run 22.5 m while B runs 25 m in the same time. In a 1000 m race, by how much distance B beats A?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 100 m
In the same time, the distances covered are in the ratio of the speeds, A : B = 22.5 : 25.
When B runs 1000 m, A runs
\( \displaystyle \frac{22.5}{25}\times 1000=900\text{ m} \)
So B beats A by 1000 − 900 = 100 m.
