Question

how much longer is the humpback than the killer whale

Answer 1

You could say that on average the humpback is 6.85 m longer, but in terms of relative size think of this problem as a ratio.  The ratio of humpback:killer = 13.7:6.85.  Written as a fraction, this is  13.7/6.85 = 2 or 2:1 in terms of the ratio.  Therefore, the length of the humpback is 2x the length of the killer on average.

 

...which is why killer whale hunt in packs...(maybe check with one of the bio folks on that!)
