An elephant calf is born at the zoo.
The elephant calf weighs 310 pounds.
Sarah weighs 63 kg.
She knows 1 kg = 2.2 pounds.
Sarah says, "The elephant calf weighs more than 2.5 times as
as I do."
Is Sarah correct?

Answer 1

No.

Explanation:

63 kg = 36 * 2.2 pounds

= 138.6 pounds.

Multiplying this by 2.5:

138.6 * 2.5

= 346.5 pounds

The calf weighs 310 pounds so that is not 2.5 times as Sarah's weight.

Answer 2

An elephant pregnancy lasts around 22 months, meaning that new born baby elephants are not small! A baby elephant is called a calf and can weigh between 200 and 300 lbs and stand about 3 feet (1 m) tall.
