Math Problem : D.1 100 m dash

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.
