Answer:
The average speed for the record time is 9.78 m/s.
Explanation:
Given that,
Total distance [tex]d= 2.00\times10^2\ km[/tex]
Time [tex]t= 5\times60\times60+40\times60+37\ sec[/tex]
[tex]t =20437\ sec[/tex]
We need to calculate the average speed for the record time
Using formula of the average speed
[tex]v_{avg}=\dfrac{D}{T}[/tex]
Where, D = total distance
T = total time
Put the value into the formula
[tex]v_{avg}=\dfrac{2.00\times10^2\times10^{3}}{20437}[/tex]
[tex]v_{avg}=9.78\ m/s[/tex]
Hence, The average speed for the record time is 9.78 m/s.
