Question

Помогите пожалуйста решить задачу:Масса угля в железном дорожном вагоне 60 т. самосвал может взять 3 часть этого груза. Сколько рейсов надо сделать нам самосвале,чтобы разгрузить 6 таких вагонов . Заранее спасибо

Answer 1

1) 60*1/3=20[тн]- сможет взять самосвал
2) 60*6=360[тн]- вес угля в  6-ти вагонах
3) 360:20=18[рейсов]- столько рейсов надо сделать на самосвале,чтобы разгрузить 6 таких вагонов

Answer 2

1) 60т : 10 *3 = 18т - вес который может отвезти самосвал за 1 ходку2) 60т *6 вагонов = 360т - общий вес 6 вагонов3)360т : 18 т = 20 рейсов нужно сделать на самосвале ,чтобы разгрузить 6 вагонов   

Answer 3

Problem Analysis

To solve this problem, we need to determine the number of trips the dump truck needs to make in order to unload 6 iron railway wagons, each weighing 60 tons. We are given that the dump truck can carry 1/3 of the weight of one wagon.

Solution

To find the number of trips the dump truck needs to make, we can follow these steps:

1. Calculate the weight of one wagon: 60 tons. 2. Calculate the weight the dump truck can carry in one trip: 1/3 of the weight of one wagon. 3. Calculate the total weight the dump truck can carry in one trip: the weight the dump truck can carry in one trip multiplied by the number of wagons. 4. Calculate the number of trips the dump truck needs to make: the total weight of all the wagons divided by the total weight the dump truck can carry in one trip.

Let's calculate each step in detail.

Step 1: Calculate the weight of one wagon

The weight of one wagon is given as 60 tons.

Answer: The weight of one wagon is 60 tons.

Step 2: Calculate the weight the dump truck can carry in one trip

The dump truck can carry 1/3 of the weight of one wagon. Therefore, the weight the dump truck can carry in one trip is:

(1/3) * 60 tons = 20 tons.

Answer: The dump truck can carry 20 tons in one trip.

Step 3: Calculate the total weight the dump truck can carry in one trip

To calculate the total weight the dump truck can carry in one trip, we need to multiply the weight the dump truck can carry in one trip by the number of wagons. Since there are 6 wagons, the total weight the dump truck can carry in one trip is:

20 tons * 6 wagons = 120 tons.

Answer: The dump truck can carry 120 tons in one trip.

Step 4: Calculate the number of trips the dump truck needs to make

To calculate the number of trips the dump truck needs to make, we need to divide the total weight of all the wagons by the total weight the dump truck can carry in one trip. Since the total weight of all the wagons is 6 wagons * 60 tons = 360 tons, and the total weight the dump truck can carry in one trip is 120 tons, the number of trips the dump truck needs to make is:

360 tons / 120 tons = 3 trips.

Answer: The dump truck needs to make 3 trips to unload 6 iron railway wagons.

Conclusion

To unload 6 iron railway wagons, each weighing 60 tons, the dump truck needs to make 3 trips, with each trip carrying 1/3 of the weight of one wagon.

Answer: The dump truck needs to make 3 trips to unload 6 iron railway wagons.
