Question

In an experiment, a tern (a seabird) was taken from its nest, flown a distance 5060 km away, and released. It found its way back to its nest after a time of 12.9 days. What is the average speed of the tern during its journey?

1) 392.2 km/day
2) 394.2 km/day
3) 396.2 km/day
4) 398.2 km/day

Answer 1

The average speed of the tern during its journey is approximately 16.35 km/h.

Step-by-step explanation:

To find the average speed of the tern during its journey, we need to divide the total distance traveled by the total time taken. In this case, the tern flew a distance of 5060 km in a time of 12.9 days.

To convert the time to hours, we multiply 12.9 days by 24 hours/day. This gives us a total time of 309.6 hours.

Now, dividing the distance by the time, we get an average speed of approximately 16.35 km/h. Therefore, none of the options provided - 392.2 km/day, 394.2 km/day, 396.2 km/day, or 398.2 km/day - are correct.
