Have you heard about marathon race in which people have to run about 40 kilometers? People run marathons on roads because the track of stadium is only 400 metres

Posted by Pankaj Kute 5 years, 1 month ago

CBSE > Class 04 > Mathematics

1 answers

Yogita Ingle 5 years, 1 month ago

1000 m = 1 km

(a) Now, 1 round of the stadium track = Length of the stadium track= 400 m

∴10 rounds of the stadium track = 10×400 m = 4000 m = (4000/1000) km = 4 km

(b) Total length of the marathon race = 40 km = 40×1000 m = 40000 m

Distance covered in 1 round of stadium track = 400 m

∴Number of rounds in 40000 m = 40000/400 = 100

So, if you run a marathon on a stadium track, you will have to complete 100 rounds
