Question

Добрый день! Как написать краткую запись задачи: Масса угля в железнодорожном вагоне 60 т. Самосвал может взять третью часть этого груза. Сколько рейсов надо сделать на самосвале, чтобы разгрузить 6 таких вагонов?

Answer 1

В вагоне 60 т
Самосвал из вагона вывозит 0.3*60=18 т за рейс
6 вагонов это 60*6=360 т / 18 = 20 рейсов
Ответ: 20 рейсов

Answer 2

Writing a Concise Problem Statement:

To write a concise problem statement for the given scenario, you can use the following approach:

Given: - The mass of coal in a railway car is 60 tons. - A dump truck can carry one-third of this load. - The task is to determine the number of trips the dump truck needs to make to unload 6 such railway cars.

Solution Approach:

To solve this problem, we can calculate the total mass of coal in the railway cars and then determine the number of trips the dump truck needs to make to unload this total mass.

Calculating the Total Mass of Coal:

The total mass of coal in the 6 railway cars can be calculated by multiplying the mass of coal in one car by the total number of cars.

The mass of coal in one car = 60 tons Total number of cars = 6

Total mass of coal = Mass of coal in one car * Total number of cars Total mass of coal = 60 tons * 6

Total mass of coal = 360 tons

Determining the Number of Trips for the Dump Truck:

Since the dump truck can carry one-third of the load in each trip, we can calculate the number of trips required by dividing the total mass of coal by the load capacity of the dump truck.

Load capacity of the dump truck = 1/3 of the mass of coal in one car Number of trips = Total mass of coal / Load capacity of the dump truck Number of trips = 360 tons / (60 tons / 3)

Number of trips = 18 trips

Therefore, the dump truck needs to make 18 trips to unload the coal from 6 railway cars.
