Taro raced with Jiro 100m dash.
Jiro was 10m this side to the goal when Taro made a goal.
If Taro starts from 10m back from a start point, who will win ?
Answer
Taro
Solution
Since Jiro can run only 90m while Taro runs 100m, Taro and Jiro stand in a line at 10m before the goal.
While running remaining 10m, Taro wins by pulling apart Jiro 1m.
