Question

The weight of a adult blue whale is 9x10^4 kilograms; the weight of an elephant is 3x10^3 kilograms. How many times heavier is the whale than the elephant?

Answer 1

30 times

Explanation:

Weight of adult blue whale =
`9 * 10^(4)` kilogram

Weight of an elephant =
`3 * 10^(3)` kilogram

In order to find how many times a quantity is as compared to the other quantity, we divide the two. So here we have to divide the weight of adult blue whale by the wight of elephant.

`(9 * 10^(4))/(3 * 10^(3))\\= 30`

This means, adult blue whale is 30 times heavier than the elephant.
