Question

A 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

Answer 1

Explanation:

Speed = distance ÷ time (seconds)

40m ÷ 10×60

1\15 m/s = Speed

Answer 2

Given:-

• Distance travelled by hummingbird ,d = 40m

• Time taken ,t = 10 min.

To Find:-

• Average speed , Av.

Solution:-

Conversion of Unit

1 min = 60s

∴ 10min = 10×60 = 600s

As we know that Average Speed is defined as the total distance travelled by a body divided by total time taken.

• Av. Speed = Total Distance/total time

• Av.Speed = d/t

Substitute the value we get

→ Av.Speed = 40/600

→ Av.Speed = 0.066 m/s

∴ The average speed of the hummingbird is 0.066 m/s.
