In a 3000 metres race people run ____ km.
There are 1000 metres in 1 kilometre. Divide 3000 by 1000 to convert 3000 metres to kilometres.

10 rounds of a stadium track = ______ km
Step 1: The track of a stadium is 400 metres. Multiply 400 by 10 to obtain the distance covered in 10 rounds of a stadium track in metres. 400 × 10 = 4000 m
Step 2: 1000 metres is equal to 1 kilometre. Divide 4000 by 1000 to convert 4000 metres to kilometres.
4000 ÷ 1000 = 4 km
Therefore, 10 rounds of a stadium track = 4 km
So, if you run a marathon on a stadium track, you will have to complete _____ rounds!
Step 1: The total distance to run in a marathon race is 40 km. Multiply 40 by 1000 to convert 40 km to metres.
40 × 1000 = 40000 km
Step 2: The distance covered in 1 round of stadium track is 400 m. Divide 40000 by 400 to get the number of rounds required to complete a marathon.
40000 ÷ 400 = 100
Therefore, you will have to complete 100 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?
Step 1: Dhanu’s jump is 3 metres 40 cm. Since Gurjeet jumps 20 cm less than Dhanu, subtract 20 cm from 3 metres 40 cm to get the length of Gurjeet’s jump.
(3 metres 40 cm) – 20 cm = 3 metres 20 cm
Step 2: Since Gopi jumps 5 cm less than Gurjeet, subtract 5 cm from 3 metres 20 cm to get the length of Gopi’s jump.
(3 metres 20 cm) – 5 cm = 3 metres 15 cm
Therefore, Gurjeet’s jump is 3 m 20 cm long and Gopi’s jump is 3 m 15 cm long.

Here are the Indian Records and World Records for some jumps.
Find out from the table:
How many centimetres more should Chandra Pal jump to equal the Men’s World Record for high jump?
The Men’s World Record for high jump is 2m 45 cm. The length of Chandra Pal high jump is 2m 17 cm. Subtract 2m 17 cm from 2m 45cm to get the answer.
(2m 45cm) – (2m 17cm) = 28 cm
Therefore, he should jump 28 cm more.
How many centimetres higher should Bobby A. jump to reach 2 metres?
Step 1: The length of Bobby A. jump is 1 m 91 cm. We know, 100 cm = 1 m. Therefore, the length of Bobby A.’s jump is:
100 cm + 91 cm = 191 cm.
Step 2: Multiply 100 by 2 to convert 2m to centimetres. 100 × 2 = 200
Step 3: Subtract 191 from 200 to get the answer.
200 – 191 = 9 Therefore, Bobby A.’s jump should be 9cm higher to reach 2m. We know, 1m = 100 cm. Therefore, half metre = 50cm
Galina’s long jump is nearly
a) 7 metres
b) 7 and a half metres
c) 8 metres
The length of Galina’s long jump is 7 m 52 cm. Half meter is equal to 50 cm. Therefore, Galina’s jump is nearly 7 and a half metres.
Hence, the option b is the correct answer
Look at the Women’s World Records. What is the difference between the longest jump and the highest jump?
Women’s World Record for longest jump is 7m 52 cm and for highest jump is 2m 9 cm.
Subtract 2m 9 cm from 7m 52 cm to obtain the difference.
(7m 52 cm) – (2m 9 cm) = 5m 43 cm
The difference between the longest and the highest jump is 5m 43 cm.
Momun comes to school from very far. He first walks about 400 metres to the pond. With slippers in his hands, he then walks 150 metres through the pond. Next he runs across the 350 metres wide green field. Then he carefully crosses the 40 metres wide road to reach his school.
How much does Momun walk every day to reach school?
Add all the distances that is covered by Momun to get the total distance he walks to reach school.
400 + 150 + 350 + 40 = 940m
Therefore, he walks 940 m every day to reach school.
If Mike P. could jump _____ centimetres longer, his jump would be full 9 metres?
The length of Mike P. jump is 8m 95 cm. We know 1m = 100 cm. Subtract 95 cm from 100 cm to obtain the difference.
100 cm – 95 cm = 5 cm
Therefore, if he could jump 5 cm longer, his jump would be full 9 metres
Whose high jump is very close to two and half metres?
a) Stefka K.
b) Chandra Pal
c) Javier S.
d) Bobby A.
Observe the record given in the table. The length of Javier S. jump is 2m 45 cm.
Half metre is equal to 50 cm. Therefore, his jump is approximately two and a half metres.
Hence, the option c) is the correct answer
The doctor has told Devi Prasad to run 2 km every day to stay fit. He took one round of this field. How far did he run?
Step 1: Add 500 m four times to obtain the distance covered in one round.
500 m + 500 m + 500 m + 500 m = 2000 m.
Step 2: We know, 1 km = 1000 m. Divide 2000 by 1000 to convert 2000 m to kilometres.
2000 ÷ 1000 = 2
Therefore, he ran 2 km in one round.
The field was very far from his home. So he chose a park nearby. The boundary of the park was about 400 metres long.
How many rounds of the park must Devi Prasad run to complete 2 km?
Step 1: Multiply 2 by 1000 to convert 2 km to metres. 2 × 1000 = 2000 m
Step 2: The distance covered in one round is 400 m. Divide 2000 by 400 to get the answer.
2000 ÷ 400 = 5
Therefore, he has to run 5 rounds of the park to complete 2 km
One day the weather was very good and a cool breeze was blowing. He felt so good that he kept jogging till he got tired after 8 rounds. That day he ran ____ km and _____ metres!
Step 1: Distance covered in one round is 400m. Multiply 400 by 8 to obtain the distance covered in 8 rounds.
400 × 8 = 3200m
Step 2: Distance covered in 8 rounds is 3200m that is 3000m + 200m. We know 1000m = 1 km. Divide 3000 by 1000 to convert 3000m to kilometres.
3000 ÷ 1000 = 3 km
Therefore, he ran 3 km and 200m.
