Respuesta :
Answser: 8 m/s
Explanation:
Sally performed an experiment, in which she handled two variables:
- distance between the feeders, and
- time to fly from one feeder to next.
The distance is fixed, so she only measured it one time and it was 24m.
She timed 10 trials and calculated the average time of 3 seconds. So, you will use this time fo calculate the average speed of the hummingbird flying from one feeder to the other, using the formula:
- speed = distance / time
- speed = 24 m / 3 s = 8 m/s.
Hence, the result is 8 m/s.
