Question

A crow picks up pebbles and puts them into a pot which is 10m away from the pot. in doing so it makes 5 trips within 80 seconds.
what is its average speed

Answer 1

Distance from pot = 10m

Total distance = 5*10 = 50m

Total time = 80sec

Average speed = $\frac{total distance}{total time}$ = $\frac{50}{80}$ = 0.625m/s

Answer 2

Answer:

1.25 m/s

Explanation:

Distance from pot = 10m

1 trip =2×10m =20m

Total distance = 5*20 = 100m

Total time = 80sec

Average speed = {total distance}/{total time} = 100m/80s

= 1.25 m/s
