Answser: 8 m/s
Explanation:
Sally performed an experiment, in which she handled two variables:
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:
Hence, the result is 8 m/s.
