Question

задача по железной дороге нужно перевезти 750 тонн зерна . Сколько для этого потребуется вагонов, вмещающих каждый по 60 тонн зерна?В скольких вагонах,вмещающих по 40 тонн, можно перевезти это же зерно?

Answer 1

1) 750/60=12,5 - надо 13 вагонов

2) 750/40=18,75 - надо 19 вагонов

Answer 2

1) 750:60=12,5 - вагонов потребуется

2) 750:40=18,75 - вагонов потребуется

Ответ: при вместимости вагона 60 тпотребуется 12 с половиной вагонов, а при вместимости вагона 40 т потребуется 18,75 вагонов.

Answer 3

Calculation for wagons that can carry 60 tons of grain

To calculate the number of wagons needed to transport 750 tons of grain, with each wagon capable of carrying 60 tons of grain, we can use the following formula:

Number of wagons = Total weight of grain / Weight capacity of each wagon

Plugging in the values:

Number of wagons = 750 tons / 60 tons

Calculating this:

Number of wagons = 12.5 wagons

Since we cannot have a fraction of a wagon, we need to round up to the nearest whole number. Therefore, we would need 13 wagons that can carry 60 tons of grain to transport 750 tons of grain.

Calculation for wagons that can carry 40 tons of grain

To calculate the number of wagons needed to transport the same amount of grain (750 tons), but with each wagon capable of carrying 40 tons of grain, we can use the same formula:

Number of wagons = Total weight of grain / Weight capacity of each wagon

Plugging in the values:

Number of wagons = 750 tons / 40 tons

Calculating this:

Number of wagons = 18.75 wagons

Again, since we cannot have a fraction of a wagon, we need to round up to the nearest whole number. Therefore, we would need 19 wagons that can carry 40 tons of grain to transport 750 tons of grain.

Please note that these calculations assume that the weight of the wagons themselves is negligible compared to the weight of the grain being transported.
