Question

Sally was trying to calculate the speed of the hummingbirds feeding outside her window. Sally measured the distance from one feeder to the next, 24 meters. Then she sat and timed how long it took a hummingbird to fly from one feeder to the next. She timed 10 trials and calculated the average time, 3 seconds. What was the average speed of the hummingbird flying from one feeder to the other?

Answer 1

Formula to calculate speed:

Speed=Distance/Time

Distance: 24 m
Time: 3 sec

24/3=8

So the correct answer is 8 m/s

Answer 2

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.
