Question

The mass of a whale is 70000 kg or 7*10^4 and the mass of elephant is 7000kg or 7*10^3. How many times more massive is the whale than the elephant?

A)20 times
B)5 times
C)15 times
D)10 times

Answer 1

By dividing the mass of the whale (7×104 kg) by the mass of the elephant (7×103 kg), we find that the whale is 10 times more massive than the elephant.

Step-by-step explanation:

To determine how many times more massive the whale is than the elephant, we divide the mass of the whale by the mass of the elephant.

Mass of whale = 70,000 kg or 7×104 kg
Mass of elephant = 7,000 kg or 7×103 kg

Dividing the mass of the whale by the mass of the elephant gives us:

7×104 kg / 7×103 kg = 10

Therefore, the whale is 10 times more massive than the elephant.
