Question

на завод отправили 3600т угля,в вагонах по 60т угля,и столькоже угля в вагонах по 90т.каких вагонов потребовалось больше и на сколько?

Answer 1

1) 3600:60=360:6=60 - вагонов по 60 тонн угля
2) 3600:90= 360:9=40 - вагонов по 90 тонн угля
3) 60 - 40 = на 20 вагонов по 60 тонн потребовалось больше ,чем по 90 тонн.

Answer 2

Calculation of the Number of Wagons Required

To determine the number of wagons required for the shipment of 3600 tons of coal, we need to calculate the number of wagons for each type of coal: 60 tons and 90 tons.

Let's start by calculating the number of wagons needed for 60 tons of coal. We can divide the total amount of coal (3600 tons) by the weight of each wagon (60 tons):

Number of wagons for 60 tons of coal = 3600 tons / 60 tons = 60 wagons

Next, let's calculate the number of wagons needed for 90 tons of coal. Again, we can divide the total amount of coal (3600 tons) by the weight of each wagon (90 tons):

Number of wagons for 90 tons of coal = 3600 tons / 90 tons = 40 wagons

Comparison of the Number of Wagons

From the calculations above, we can see that 60 wagons are required for 60 tons of coal, while only 40 wagons are required for 90 tons of coal.

Therefore, more wagons are required for 60 tons of coal, and the difference in the number of wagons is 60 - 40 = 20 wagons.

Please note that the information provided is based on the assumption that each wagon can carry only one type of coal. If the wagons can carry a mix of coal weights, the calculation may differ.
