<em><u>Solution:</u></em>
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
<u><em>The speed is given by formula:</em></u>
From given information,
We know that,
Therefore,
Substituting the values in above formula,
Thus average speed is 18.4366 miles per hour
<em><u>Let us convert to feet per hour</u></em>
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
