Final answer:
To convert a bottlenose dolphin's speed from 2.68 meters per second to miles per hour, first convert to kilometers per hour and then to miles per hour, resulting in approximately 6.00 mph.
Step-by-step explanation:
To find the dolphin's speed in miles per hour, we must convert the speed from meters per second to miles per hour. Here are the conversion steps:
- First, we convert the speed from meters per second to kilometers per hour, since 1 kilometer equals 1,000 meters, and there are 3,600 seconds in an hour (1 hour = 60 minutes * 60 seconds).
2.68 m/s * (1 km / 1,000 m) * (3,600 s / 1 hr) = 9.648 km/hr
- Now, we need to convert kilometers per hour to miles per hour. Knowing that 1 mile is approximately 1.60934 kilometers, we divide the speed in kilometers per hour by this conversion factor.
9.648 km/hr / 1.60934 km/mile = 5.995 mph (rounded to three decimal places)
Therefore, the dolphin's speed is approximately 6.00 miles per hour.
