Important Facts and Formulae:

Races:
A contest of speed in running ,riding,driving,sailing or rowing is called a Race

Race Course:
The ground or path on which contests are made is called a race course

Starting Point:
The point from which a race begins is called starting point.

Winning point or goal:
The point set to bound a race is called a winning point.

Dead Heat Race:
If all the persons contesting a race reach the goal exactly at the same time,then the race is called a dead heat race.

Start:
Suppose A and B are two contestants in a race .If before the start of the race,A is at the satrtint point and B is ahead of A by 12 metres. Then we say that "A gives B a start 12 metres.

->To cover a race of 100metres in this case,A will have to cover 100m while B will have to cover 88m=(100-12)

->In a100m race 'A can give B 12m' or 'A can give B a start of 12m' or 'A beats B by 12m'means that while A runs 100m B runs 88m.

Games:
A game of 100m,means that the person among the contestants who scores 100 points first is the winner.

If A scores 100 points while B scores only 80 points then we say that 'A can give B 20 points'.
