Question

Розв'яжи задачу двома способами. Три самоскиди за 4 рейси привезли на будівельний майданчик 60 000 кг піску. Скільки тонн піску зможуть привезти ці самоскиди за 8 рейсів?​

Answer 1

4 рейси-60000кг

8рейсів-?т

Розв'язання

1 спосіб

1)60000•2=120000(кг)

120000кг—120т

Відповідь:120 тонн піску зможуть привезти ці самоскиди за 8 рейсів

2 спосіб

1)60000:4=15000(кг)-за 1 рейс

2)15000•8=120000(кг)

120000кг—120т

Відповідь:120 тонн піску зможуть привезти ці самоскиди за 8 рейсів.

Answer 2

To solve this problem, we can use two different methods: the ratio method and the unitary method.

Method 1: Ratio Method

1. Determine the ratio of the weight of sand to the number of trips made by the dump trucks. In this case, the dump trucks made 4 trips and delivered 60,000 kg of sand. Therefore, the ratio is 60,000 kg / 4 trips = 15,000 kg/trip. 2. Use the ratio to find the weight of sand that can be delivered in 8 trips. Multiply the ratio by the number of trips: 15,000 kg/trip * 8 trips = 120,000 kg.

Therefore, the dump trucks will be able to deliver 120,000 kg (or 120 tons) of sand in 8 trips.

Method 2: Unitary Method

1. Determine the weight of sand delivered per trip. In this case, the dump trucks delivered 60,000 kg of sand in 4 trips. Therefore, the weight of sand delivered per trip is 60,000 kg / 4 trips = 15,000 kg/trip. 2. Use the weight of sand delivered per trip to find the weight of sand that can be delivered in 8 trips. Multiply the weight of sand per trip by the number of trips: 15,000 kg/trip * 8 trips = 120,000 kg.

Therefore, the dump trucks will be able to deliver 120,000 kg (or 120 tons) of sand in 8 trips.

Both methods yield the same result: the dump trucks will be able to deliver 120,000 kg (or 120 tons) of sand in 8 trips.
