The athlete will travel 4.5 kilometers in 30 minutes if they run at the same average speed of 9 kilometers per 1 hour

Answer 2

The athlete can cover 4.5 km in 30 minutes. Hence, option C is correct.

Important information:

• An athlete can run 9 kilometers in 1 hour.

We need to find the distance covered by the athlete in 30 minutes.

Average speed:

We know that 1 hour = 60 minutes. So,

The distance covered in 60 minutes is 9 km.

The distance covered in 1 minute is $\dfrac{9}{60}$ km.

The distance covered in 30 minutes is $\dfrac{9}{60}\times 30=4.5$ km.

Therefore, the athlete can cover 4.5 km in 30 minutes. Hence, option C is correct.
