The average length of a humpback whale is 13.7 meters. The average length of a killer whale is 6.85 meters. How much longer is the humpback whale than the killer whale?

Answer 1

The difference in length between the humpback whale and the killer whale is calculated by subtracting the length of the killer whale from the length of the humpback whale:

13.7 meters - 6.85 meters = <<13.7-6.85=6.85>>6.85 meters.

Therefore, the humpback whale is 6.85 meters longer than the killer whale.
