2. The kit's calf is twenty times heavier than the elephant's calf. The mother elephant is 50 times heavier than her calf and 30 times lighter than the mother whale, and she weighs 6 tons. How heavy is the elephant's calf, how heavy is the kit's calf, and how heavy is the mother whale? How many times heavier is the mother whale than her calf?
## 2. First way:

The mother elephant weighs 6 tons, i.e., $6000 \mathrm{~kg}$.

Since $180000 \mathrm{~kg}$ : $2400 \mathrm{~kg}=75$, we conclude that the mother whale is 75 times heavier than her calf.

(Or:

The mother whale is heavier than the baby elephant by $30 \cdot 50=1500$ times.

Since the baby whale is 20 times heavier than the baby elephant, we conclude that the mother whale is $1500: 20=75$ times heavier than the baby whale.
