Question

The weight of an adult blue whale is 9 × 104 kilograms; the weight of an elephant is 3 × 103 kilograms. How many times heavier is the whale than the elephant?

Answer 1

9•10^4 / 3•10^3 = 30. The whale has 30 times the mass of the elephant, or 29 times more. For that reason, it's 29 times heavier than the elephant.

Answer 2

Answer:

The whale is $30$ times heavier than the elephant

Step-by-step explanation:

we have that

The weight of an adult blue whale is $9*10^{4} \ kg$

The weight of an elephant is $3*10^{3} \ kg$

To find how many times heavier is the whale than the elephant

Divided the weight of the whale by the weight of the elephant

so

$\frac{9*10^{4}}{3*10^{3}} =3*10^{4-3}=3*10=30$
