Answer 2

Answer:

Answer B: $1*10^2$ times

Step-by-step explanation:

To find how many times more massive is the whale relative o the polar bear, we just need to find the quotient of one over the other:

$\frac{7*10^4}{7*10^2} = \frac{7*10^2*10^2}{7*10^2}=1*10^2$ times

Therefore our answer agrees with the one shown as answer B.
