Write a maths equation to work out the following sums. 

1. Find out how long the Grand National race is at Aintree, held every year. The calculate how far apart the fences are if there are 30 in total.

2. If the fastest horse travelled at a speed of 25 km / hour, how long did it take to reach the finishing line ?

3. The slowest horse travelled at a speed of 15 km / hour – how much further behind the winning horse was he at the finishing line ?

4. There were 60 horses running in the race and 10 % of them were white, 1 : 5 were black and one quarter were brown. How many of each colour horse was there ?

5. One fifth of the riders wore red silks, 1 : 3 wore blue and 5% wore green. The rest of the riders wore pink silks. Work out how many of each colour silks the riders wore.

6. Three of the horse fell at the first fence, 5 fell at the third, 8 fell between the water jump and Beecher’s Brook. If 60 horses started the race, how many horse were left running ?

7. 5, 000 spectators came to watch the race. Each paid £5 per ticket. How much is that in total ?

8. The odds on one horse were 2 : 1 of it winning. If there were 60 horses in the race, what were the odds of the others winning ?

9. Work out the difference in the weight of the lightest horse (575 kg) and the heaviest horse (725 kg).

Answers :

1. x / 30 = …

2.

3.

4. a) white = 60 / 100 x 10 = 6 ; b) black = 10 ; c) brown – 60 / 4 = 15

5. a) red – 60 / 5 = 12 ; b) blue – 15 ; c) green – 60 / 100 x 5 = 3 ; d) pinks – 60 – (12 + 15 + 3 = 30) = 30

6. 60 – (3 + 5 + 8 = 16) = 44

7. 5000 x 5 = £25 , 000

8. one horse 40 : 20, therefore, 20 : 40

9. 150 kg
