Have you heard about marathon races in which people have to run about 40 kilometres? People run marathons on roads because the track of a stadium is only 400 metres.
(a) 10 rounds of a stadium track = ________ km
Answer: 10 rounds of a stadium track = 400 metres × 10
= 4000 metres
= 400 ÷ 1000
= 4 km
So, 10 rounds of a stadium track = 4 km
(b) So, if you run a marathon on a stadium track, you will have to complete rounds!

Dhanu has the longest jump of 3 metres 40 cm. Gurjeet is second. His jump is 20 cm less than Dhanu’s. Gopi comes third. His jump is only 5 cm less than Gurjeet’s jump.
How long are Gurjeet’s and Gopi’s jumps?

Therefore, Gurjeet’s jump is 3 metres 20 cm
Gopi’s jump = Gurjeet’s jumps – 5 cm

Therefore, Gopi’s jump is 3 metres 15 cm
Find out from the table
1. How many centimetres more should Chandra Pal jump to equal the Men’s World Record for high jump?
Answer: We know that,
1 m = 100 cm
Men’s world record for high jump = 2 m 45 cm
= 2 × 100 + 45 cm
= 200 cm + 45 cm
= 245 cm
High jump record of Chandra Pal = 2 m 17 cm
= 2 × 100 + 17 cm
= 200 cm + 17 cm
= 217 cm
Now, subtract 217 from 245, we get
245 – 217 = 28 cm
Hence, to equal the men’s world record for high jump, Chandra Pal need to jump 28 cm more.
2. How many centimetres higher should Bobby A jump to reach 2 metres?
Remember that 1 m = 100 cm
Half metre =?
Answer: Bobby A, high jump record = 1 m 91 cm
= 1 × 100 + 91 cm
= 191 cm
Required centimetres to reach is 2m
= 2 × 100
= 200 cm
200 – 191 = 9 cm
Therefore, Bobby A should jump 9 cm higher to reach 2 metres

So, difference between them is
= 7 m 52 cm – 2 m 9 cm
= 5 m 43 cm
5. If Mike P, could jump _______ centimetres longer, his jump would be full 9 metres.
Answer: Mike P long jump record = 8 m 95 cm

Answer: We know that,
1 km = 1000 m

3000 m = 3000 ÷ 1000
= 3 km 200 m
Hence, Devi Prasad ran 3 km 200 m to complete 8 rounds of the park
