The average speed is 97346 feet per hour approximately
<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

<u>Given </u><u>:</u><u>-</u><u> </u>
- C is the midpoint of BD .
- BC = x + 7
- CD = 8x
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>
<u>Answer</u><u> </u><u>:</u><u>-</u><u> </u>
As C is the midpoint , we can say that the line is BCD . So that ,
Substitute the values ,
- ( x+7 ) + 8x = BD
- BD = x + 8x + 7
- BD = 9x + 7 .
<u>Hence</u><u> the</u><u> </u><u>value</u><u> of</u><u> </u><u>BD </u><u>is </u><u>9</u><u>x</u><u> </u><u>+</u><u> </u><u>7</u><u> </u><u>.</u>
