Answer:
<em>The correct option is: 32.4 km/h</em>
Step-by-step explanation:
The fastest recorded speed of a turtle while swimming is 9 m/s.
Now, 9 m/s
1 kilometer= 1000 meter
So, 1 meter kilometer
and <u>9 meters</u> kilometer
Now, 1 hour = 3600 seconds
So, <u>1 second</u>

So, the speed of the turtle will be 32.4 km/h.
Option D. 2(n + 9) is the right answer
Step-by-step explanation:
The word problems are converted into mathematical problems to solve simply.
for the given problem
"two times the sum of a number and 9"
Let n be a number then
when there is and between two things they are performed first then next operation is performed so
the sum of a number and 9
Then
two times the sum of a number and 9
Hence,
Option D. 2(n + 9) is the right answer
