If a long run athlete can run 1/2 km in 3 minutes then he can run 10 km in an hour.
Given, a long distance athlete can run 1/2 kilometer in 3 minutes.
How much distance can he cover in an hour = ?
How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.
Time = 60 minutes.
we know that 3 minutes = 1/2 km
therefore, distance covered in an hour = 1/2 ÷ 3/60
= 1/2 × 60/3
= 1/2 × 20
= 10
distance covered in an hour = 10 km.
hence we get the distance covered by the athlete in an hour as 10 km.
