Given,

The length of the race = 500 metres

The speed of the athlete = 50 km/h

To find,

The time taken by that athelete to complete the race.

Solution,

We can solve this problem by using the normal arithmetical method.

So,

The athelete runs 50 km in = 1 hour

The athelete runs 50000 m in = 3600 seconds

The athlete runs 1 m in = 3600/50000 seconds

The athelete runs 500 m in = 500×3600/50000 = 36 seconds

Hence,the athelete will take 36 seconds to complete the race.
