Answer:
To calculate the speed of the fish, we divide the distance traveled by the time taken.
Distance traveled: 639.1 miles
Time taken: 2.34 days
To convert the distance and time to metric base units, we can use the following conversions:
1 mile = 1.60934 kilometers
1 day = 24 hours
Distance in kilometers:
639.1 miles * 1.60934 kilometers/mile = 1028.02 kilometers
Time in hours:
2.34 days * 24 hours/day = 56.16 hours
Now, we can calculate the speed in metric base units by dividing the distance by the time:
Speed = Distance / Time
Speed = 1028.02 kilometers / 56.16 hours
Calculating the speed:
Speed ≈ 18.31 kilometers/hour
Therefore, the fish is swimming at a speed of approximately 18.31 kilometers per hour.
