The average weight of a blue whale is 4 * 10 ^ 5 pounds. The average weight of an elephant is 1 * 10 ^ 4 pounds. Approximately how many times heavier is a blue whale than an elephant in pounds?
O 4 times heavier.
2 times heavier.
40 times heavier.
To determine the answer, we need to find the ratio between the weight of a blue whale and the weight of an elephant.
The weight of a blue whale is 4 * 10^5 pounds, and the weight of an elephant is 1 * 10^4 pounds.
To find the ratio, we divide the weight of the blue whale by the weight of the elephant: (4 * 10^5) / (1 * 10^4)
Simplifying this expression gives us 40.
So, a blue whale weighs approximately 40 times more than an elephant.
