As the question says, the longest blue whale was about 18 scuba divers in length.
We are supposed to use breaking apart to estimate the length of that blue whale.
Now, the average height of a scuba diver is 165.5 centimeters.
The length is roughly equivalent to the length of 18 scuba divers.
Therefore, the combined length of 18 scuba divers is :
[tex]18 \times 165.5 =2979 cm[/tex]
Hence, the length of the blue whale is about 2979 cm.
We can also convert centimeters into meters by dividing the centimeters by 100.
We get, [tex]\frac{2979}{100}=29.79m[/tex]
So the length of the blue whale in meters is 29.79 meters.
