Question

На товарную станцию пригнали состав с солью из 10 вагонов.В каждом вагоне было 85 т соли.Одна машина за один рейс может огвезти на склад 3т 6ц,а другая-14т 2ц соли.Каждая машина сделала 10 рейсов.Сколько соли осталось ещё вывезти?

Answer 1

Пишем условие чтобы все видеть что есть и нету; состав 1 с вагонами =10штук; соль =по 85т в 1 вагоне; 1машина за 1 рейс= 3т 6ц; 2 машина за 1 рейс= 14т 2ц; 1машина= 10рейсов сделала и 2машина= 10 рейсов сделала; осталось соли вывезти=? 1тонна=10центнеров; 1) 85т*10вагонов=850 тонн привезли всего соли или в центнерах 85*10=850ц; 850*10рейс=8500ц ; ; 2) 3т 6ц* 10рейс= 36т или 3*10=30ц; (30+6)*10рейсов= 360центнеров; это первая машина перевезла на склад всего соли; 3) 14т 2ц* 10рейс= 142т или 14*10= 140ц; (140+2)*10рейс=1420центнеров перевезла всего соли на склад вторая машина; 4) 36т+142т=178т перевезли вместе две машины; или в центнерах 360+1420=1780ц; 5) 850т- 178т=672т осталось вывезти; или 8500-1780=6720центнеров осталось вывезти; Ответ: осталось вывезти ещё 672тонны соли

Answer 2

Calculation of the Total Salt Quantity

To calculate the total quantity of salt that was brought to the goods station, we need to multiply the number of wagons by the quantity of salt in each wagon. In this case, there were 10 wagons, and each wagon contained 85 tons of salt.

Therefore, the total quantity of salt brought to the goods station is 10 wagons * 85 tons/wagon = 850 tons.

Calculation of Salt Transported by Each Truck

Next, let's calculate how much salt each truck can transport in one trip.

The first truck can transport 3 tons and 6 hundredweights (1 hundredweight = 50.8 kilograms) per trip. To convert hundredweights to tons, we divide by 20 (since there are 20 hundredweights in a ton). Therefore, the first truck can transport:

3 tons + (6 hundredweights / 20) tons = 3.3 tons per trip.

The second truck can transport 14 tons and 2 hundredweights (1 hundredweight = 50.8 kilograms) per trip. Using the same conversion, the second truck can transport:

14 tons + (2 hundredweights / 20) tons = 14.1 tons per trip.

Calculation of Total Salt Transported by Each Truck

Now, let's calculate the total quantity of salt transported by each truck during the 10 trips.

The first truck can transport 3.3 tons per trip, and it made 10 trips. Therefore, the total quantity of salt transported by the first truck is:

3.3 tons/trip * 10 trips = 33 tons.

The second truck can transport 14.1 tons per trip, and it also made 10 trips. Therefore, the total quantity of salt transported by the second truck is:

14.1 tons/trip * 10 trips = 141 tons.

Calculation of Remaining Salt to be Transported

To calculate the remaining salt that needs to be transported, we subtract the total quantity of salt transported by both trucks from the total quantity of salt brought to the goods station.

Total quantity of salt transported by both trucks = 33 tons + 141 tons = 174 tons.

Remaining salt to be transported = Total quantity of salt brought to the goods station - Total quantity of salt transported by both trucks.

Remaining salt to be transported = 850 tons - 174 tons = 676 tons.

Therefore, there is still 676 tons of salt that needs to be transported from the goods station.
