In the Netherlands there is an annual ice-skating race called the "Tours of the eleven towns" the total distance of the course is 2.00*10 squared km and the record time is 5 hours, 40 minutes, and 37 seconds. Calculate the average speed for the record time.
1hr=60mins
5hr=5 × 60=300+40=340mins
1min=3600secs
340Mins=3600×340=1224000secs/10mins
2000÷10=200km/mins
Answer:
The average speed for the record time is 9.78 m/s.
Explanation:
Given that,
Total distance \(d= 2.00\times10^2\ km\)
Time \(t= 5\times60\times60+40\times60+37\ sec\)
\(t =20437\ sec\)
We need to calculate the average speed for the record time
Using formula of the average speed
\(v_{avg}=\dfrac{D}{T}\)
Where, D = total distance
T = total time
Put the value into the formula
\(v_{avg}=\dfrac{2.00\times10^2\times10^{3}}{20437}\)
\(v_{avg}=9.78\ m/s\)
Hence, The average speed for the record time is 9.78 m/s.
