Stephen Road his bike on a road for a six hour period. On average, keep past 1 km marker every 8 minutes during this period. What was his average speed for this 6 hour period?

4.6 x10^-2m/s

Explanation:

Using the formula

Average speed =total distance/total time

Total distance = 1x1000=1000m

Total time = 6 x60 x60=21,600sec.

Av =1000/21600 =4.6 x 10^-2m/s

4.6 x 10^-2m/s

Explanation:

Average speed = total distance / total time

Total distance = 1x1000=1000m

Total time = 6 x 60 x 60=21,600sec.

Average speed =1000/21600 =4.6 x 10^-2m/s
