Question

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 104

kg.
The mass of a male polar bear is about 700 kg, or 7 x 10² kg.
About how many times more massive is the right whale than the polar bear?

Answer 1

The right whale is 100 times more massive that the polar bear

Explanation:

7 x 10^2 = 700 kg

7 x 10^4 = 70,000kg.

• 70,000 / 700 = 100

Check: 700 x 100 = 70,000

(the equivalent mass of 10 polar bears equals that of one whale)
