Answer 2

Answer:

Shyam would take $2.4$ minute to run a $800$ metre race.

Step-by-step explanation:

In context to question asked,

• We have to find the time that would take by Shyam to run a $800$ metre race​.
• It is given that As we Shyam runs at a speed of 20 km per hour.
• The formula for speed is given by,

    Speed = $\frac{Distance }{Time}$

              = $\frac{20*1000}{60}$

              = $333.33$ m per minute

• Now, to find the time to run a $800$ metre race, we have

           Speed = $\frac{Distance }{Time}$

             $333.33=\frac{800}{t}$    

           ∴ Time = $\frac{800}{333.33}$

            ∴ Time = $2.4$ minute

• ∴  Shyam would take $2.4$ minute to run a $800$ metre race.
