- 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 known as a starting point.
- Winning Point or Goal: The point set to bound a race is called a winning point or a goal.
- Winner: The person who first reaches the winning point is called a winner.
- Dead Heat Race: If all the persons contesting a race reach the goal exactly at the same time, the race is said to be 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 starting point and B is ahead of A by 12 metres, then we say that ‘A gives B, a start of 12 metres’.To cover a race of 100 metres in this case, A will have to cover 100 metres while B will have to cover only (100 – 12) = 88 metres.In a 100 race, ‘A can give B 12 m’ or ‘A can give B a start of 12 m’ or ‘A beats B by 12 m’ means that while A runs 100 m, B runs (100 – 12) = 88 m.
- Games: ‘A game of 100, 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’.
2. A and B take part in 100 m race. A runs at 5 kmph. A gives B a start of 8 m and still beats him by 8 seconds. The speed of B is: A. 5.15 kmph B. 4.14 kmph C. 4.25 kmph D. 4.4 kmph
Answer: Option B
A’s speed = 5 x 5 m/sec = 25 m/sec. 18 18 Time taken by A to cover 100 m = 100 x 18 sec = 72 sec. 25
Time taken by B to cover 92 m = (72 + 8) = 80 sec.
B’s speed = 92 x 18 kmph = 4.14 kmph. 80 5
In a 500 m race, the ratio of the speeds of two contestants A and B is 3 : 4. A has a start of 140 m. Then, A wins by:
In a 100 m race, A beats B by 10 m and C by 13 m. In a race of 180 m, B will beat C by:
At a game of billiards, A can give B 15 points in 60 and A can give C to 20 points in 60. How many points can B give C in a game of 90?
In a race of 200 m, A can beat B by 31 m and C by 18 m. In a race of 350 m, C will beat B by:
In 100 m race, A covers the distance in 36 seconds and B in 45 seconds. In this race A beats B by:
