A canada goose flew 860 km from washington to British COlumbia with an average velocity of 30.5 m/s [N]. Approximately how long did it take the goose to make its journey?
A. 0.04 h
B. 7.8 h
C. 28.2 h
D. 469.9 h
I say C.
I will be happy to critique your thinking.
7.8
To determine how long it took the goose to make its journey, we can use the formula:
time = distance / velocity
First, let's convert the average velocity from meters per second (m/s) to kilometers per hour (km/h) since the given distance is in kilometers.
1 meter per second (m/s) = 3.6 kilometers per hour (km/h)
Average velocity = 30.5 m/s * 3.6 km/h = 109.8 km/h
Now we can calculate the time:
time = distance / velocity = 860 km / 109.8 km/h
Calculating this gives us:
time ≈ 7.823 hours
So, the approximate time it took the goose to make its journey is 7.823 hours.
Comparing this with the options provided, we can see that option B (7.8 hours) is the closest match. Therefore, your answer, C, seems to be incorrect. The correct answer is B.
