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

10*85=850т. солі в 10 вагонах. 3,6*10=36 т . солі відвезла за 10 рейсів перша машина. 14,2*10=142т. солі відвезла за 10 рейсів друга машина. 36+142=178т. відвезли дві машини разом. 850-178=672 т. солі залишилося вивезти.

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 of salt [[1]].

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) of salt.

To convert hundredweights to tons, we need to divide the number of hundredweights by 20 (since 1 ton is equal to 20 hundredweights). Therefore, the first truck can transport:

3 tons + (6 cwt / 20) tons = 3.3 tons of salt per trip.

Similarly, the second truck can transport:

14 tons + (2 cwt / 20) tons = 14.1 tons of salt per trip [[2]].

Calculation of the Total Salt Quantity Transported by Each Truck

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

For the first truck: 3.3 tons/trip * 10 trips = 33 tons of salt transported.

For the second truck: 14.1 tons/trip * 10 trips = 141 tons of salt transported [[3]].

Calculation of the Remaining Salt Quantity

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

Total salt quantity brought to the station: 850 tons Total salt quantity transported by both trucks: 33 tons + 141 tons = 174 tons

Remaining salt quantity = Total salt quantity brought to the station - Total salt quantity transported by both trucks Remaining salt quantity = 850 tons - 174 tons = 676 tons of salt remaining to be transported [[4]].

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