Question

An atheletic complete of daimeter 70m in 20sec find out thedistance​

Answer 1

Answer:

219.8 metres

Explanation:

Given :

• Diameter of the circular track in which athlete runs = 70 metres

• Time the athlete ran for = 20 seconds

To find :

• Find out the total distance covered

Radius of the circular track = 70/2 = 35 metres

Circumference of the circular track = 2×3.14×35

Circumference of the circular track = 6.28×35

Circumference of the circular track = 219. 8 metres

The athlete covers a distance of 219.8 metres

Additional calculations (extra dose) :

Speed = distance / time

Speed = 219.8/20

Speed = 10.99 m/s

Answer 2

Given:-

• Diameter of circle =70m

• Time taken (t) =20s

To Find:-

• Distance covered by athlete.

Solution :-

We know that Diameter =2× Radius

∴ Radius =70/2=35 m

Distance covered =2πr

➦ Distance = 2× 22/7 × 35

➦ Distance = 44× 5

➦ Distance = 220

∴The distance covered by athlete is 220m.

➦Speed =distance /time

➦speed =220/20

➦ speed =11m/s

∴The speed of athletes is 11m/s
