Races and Games — Questions and Answers

Races and Games is Time and Distance dressed in sporting language. "A beats B by 20 m" means that when A finishes the full distance, B is still 20 m short — that single translation converts every race question into a speed ratio. Game questions work the same way, with points replacing metres.

Races and Games— Concepts, Formulas & Shortcuts

  • "A beats B by x metres" ⇒ when A covers the full distance d, B has covered d − x. Speed ratio A : B = d : (d − x).
  • "A gives B a start of x metres" ⇒ B runs only d − x while A runs d.
  • "A gives B a start of t seconds" ⇒ B begins t seconds earlier; equate the times.
  • A dead heat means both finish together — their times are equal.
  • "A game of 100" means the first player to score 100 points wins.
  • "A can give B 20 points in a game of 100" ⇒ when A scores 100, B scores 80.

Races and Games — Frequently Asked Questions

What does "A beats B by 10 m in a 100 m race" tell me?+

When A has run the whole 100 m, B has run only 90 m in the same time. Since the times are equal, the speeds are in the ratio 100 : 90 = 10 : 9.

How do I combine two games results?+

Convert both to a common scale. If A : B = 100 : 80 and A : C = 100 : 72, then B : C = 80 : 72 = 100 : 90, so B can give C 10 points in a game of 100.
