Answer 1

Answer:

Karthik

Explanation:

As per the provided information in the given question, we have:

• Arun completed a 100 meter race in 16 seconds.
• Karthik completed a 100 meter race in 13 seconds.

We've to find who ran faster.

In order to find that so, firstly we need to find the speed of both Arun and Karthik and then by comparing their speeds, we can easily find out who ran faster.

Speed of Arun :

↠⠀Speed = Distance ÷ Time

• Distance covered by Arun = 100 m
• Time taken by Arun = 16 s

↠⠀Speed of Arun = 100 m ÷ 16 s

↠⠀Speed of Arun = 6.25 m/s

Speed of Karthik :

↠⠀Speed = Distance ÷ Time

• Distance covered by Karthik = 100 m
• Time taken by Karthik = 13 s

↠⠀Speed of Karthik = 100 m ÷ 13 s

↠⠀Speed of Karthik = 7.69 m/s

By comparing their both speeds, we get that :

• Speed of Karthik > Speed of Arun

Therefore, Karthik ran faster.

• Speed is defined as the distance covered per unit time.

• It is a scalar quantity.

• Its SI unit is m/s.

• Speed of any vehicle is measured by speedometer.

• Speed = Distance ÷ Time

• Average speed is defined as the total distance covered divided by total time taken.
