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

3т 6ц=36 ц  36·10= 360 ц = 36 т соли вывезла одна машина
142 ·10= 1420 ц = 142 т соли вывезла другая машина 
142 +36= 178 т соли вывезли всего
85·10=850 т соли всего было 
850 - 178= 672 т осталось вывезти 

Answer 2

Calculation of the Total Salt Quantity

To calculate the total quantity of salt that was brought to the 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 station is 10 wagons * 85 tons/wagon = 850 tons.

Calculation of the Salt Quantity Transported by Each Truck

Next, let's calculate the quantity of salt that each truck can transport in one trip. The first truck can transport 3 tons and 6 hundredweights (cwt), while the second truck can transport 14 tons and 2 hundredweights (cwt).

To convert hundredweights to tons, we need to remember that 1 hundredweight is equal to 0.05 tons. Therefore, the first truck can transport 3.3 tons (3 tons + 6 cwt * 0.05 tons/cwt), and the second truck can transport 14.1 tons (14 tons + 2 cwt * 0.05 tons/cwt).

Calculation of the Salt Quantity Transported by Each Truck in 10 Trips

Since each truck made 10 trips, we can calculate the total quantity of salt transported by each truck by multiplying the quantity transported in one trip by the number of trips.

For the first truck: 3.3 tons/trip * 10 trips = 33 tons For the second truck: 14.1 tons/trip * 10 trips = 141 tons

Calculation of the Remaining Salt Quantity

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

Remaining salt quantity = Total salt quantity - (Quantity transported by first truck + Quantity transported by second truck) Remaining salt quantity = 850 tons - (33 tons + 141 tons)

Therefore, the remaining quantity of salt that still needs to be transported is 676 tons.

Please note that the calculations provided above are based on the information given in the question.
