Question

Новорожденный китенок весил 800кг. через несколько месяцев его масса увеличилась в 5 раз. взрослый кит весит 360 ц. во сколько раз кит тяжелее подросшего китенка? (сначала вырази их массу в одинаковых единицах.)

Answer 1

800 кг = 8 ц
1) 8ц * 5 = 40ц
360 ц : 40 ц = 8 (раз) 
Отевет: В 8 раз вес взрослой особи больше, чем маленькой

Answer 2

Calculation of the Weight Difference

To determine how much heavier the adult whale is compared to the grown-up calf, we need to express their masses in the same units.

Given: - The newborn calf weighed 800 kg. - After several months, its mass increased by a factor of 5. - An adult whale weighs 360 tons.

To compare their masses, we need to convert the adult whale's weight from tons to kilograms. Since 1 ton is equal to 1000 kilograms, the adult whale weighs 360 * 1000 = 360,000 kilograms.

Now, let's calculate the weight difference:

The grown-up calf's mass after several months is 800 kg * 5 = 4,000 kilograms.

Therefore, the adult whale is 360,000 kilograms / 4,000 kilograms = 90 times heavier than the grown-up calf.

Answer

The adult whale is 90 times heavier than the grown-up calf.
