humming bird flits from flower to flower. Over a period of 10 minutes, it travels 40 meters. The average speed of the humming bird is ___m/min.

Respuesta :

As we know that average speed is given by the ratio of total distance covered and total time of motion so we will have

[tex]v_{avg} = \frac{distance }{time}[/tex]

now we have

distance covered = 40 meter

time taken by the bird = 10 minutes

now in order to find the average speed of the bird

[tex]v_{avg} = \frac{40}{10}[/tex]

[tex]v_{avg} = 4 meter/min[/tex]

so the average speed of the bird is 4 m/min
