The average speed is 97346 feet per hour approximately
Solution:
Given that blue whale calf swam from Miami, Florida, to Havana, Cuba, a distance of 228 miles, in 12 hours 22 minutes
To find: average rate of speed in feet per hour
The speed is given by formula:
[tex]speed = \frac{distance}{time}[/tex]
From given information,
[tex]distance = 228 \text{ miles }[/tex]
[tex]time = 12 \text { hours } 22 \text{ minutes }[/tex]
We know that,
[tex]1 \text{ minute } = \frac{1}{60} \text{ hour}[/tex]
Therefore,
[tex]12 \text { hours } 22 \text{ minutes } = 12 + \frac{22}{60} \text{ hour } = 12.3667 \text{ hour }[/tex]
Substituting the values in above formula,
[tex]\text { speed }=\frac{228}{12.3667}=18.4366[/tex]
Thus average speed is 18.4366 miles per hour
Let us convert to feet per hour
We know that,
1 mile = 5280 feet
Therefore,
18.4366 miles = 18.4366 x 5280 feet = 97345.248 feet
Thus average speed is 97346 feet per hour approximately
