If Jane was beaten by 0.25 m, then Jane covered 99.75m in the time that Karen took to cover 95m (since Karen had a 5m headstart).
Jane gained 4.75 m over karen in 99.75 m.
Therefore, Jane would have gained 1m over Karen in (99.75/4.75) = 21 m.

Therefore, Jane would have covered the remaining 0.25m over Karen in 21*0.25=5.25m.

Hope this helps.


Excellent solution. Very helpful. Thanks.

I get 5 meters (more than 100 m )

Are we getting the same results? is your answer "5.25m more" based on 99.75m or 100 m?

I think it depends on who you are measuring from. If you are measuring for Karen - then it's 5, if you're measuring for Jane, then it's 5.25 - as she's 0.25 behind.
