Question

Лифт может перевозить 4 взрослых если масса каждого не больше 90 кг. Сможет ли этот лифт перевезти 5 взрослых человек если масса каждого 72кг?

Answer 1

Да, сможет. 
Рассчитаем максимальную нагрузку на лифт: 4*90кг=3600кг
Если 5 человек весят 72кг, то нагрузка на лифт в этом случае будет равна: 5*72кг=3600кг

Answer 2

4*90=360кг
5*72=360кг
да

Answer 3

Can a lift carry 5 adults if each person weighs 72 kg?

To determine if a lift can carry 5 adults, each weighing 72 kg, we need to consider the weight capacity of the lift. According to the given information, the lift can carry 4 adults if each person weighs no more than 90 kg.

Since the weight of each person is 72 kg, we can calculate the total weight of the 5 adults as follows:

Total weight = 5 adults * 72 kg/adult = 360 kg

To determine if the lift can carry this weight, we compare it to the weight capacity of the lift, which is 90 kg per person. Since the total weight of the 5 adults (360 kg) exceeds the weight capacity of the lift (90 kg per person), the lift will not be able to carry all 5 adults safely.

Therefore, the lift will not be able to carry 5 adults if each person weighs 72 kg
