Question

Винтик и Шпунтик смастерили машину «Тяни-толкай», которая едет вперед на сиропчике с расходом топлива 3л/км, а назад – на апельсиновом соке с расходом топлива 5л/км. Выехав из дома вместе, они вели машину по очереди. Винтик проехал за рулём в обе стороны 12 км. Шпунтик ехал вперед вдвое меньше, чем Винтик, а назад проехал вдвое больше, после чего имевшиеся 75 литров топлива закончились. Сколько километров Винтику и Шпунтику придется возвращаться домой пешком? помогите

Answer 1

обозначаешь за x - км проеал вперед Шпунтик, через x выражаешь сколько км вперед проехал Винтик. Потом вводишь y - проехал назад Винтик, потом выражаешь сколько проехал назад Шпунтик, потом уравнение 3x*3 + 3y*5 = 75, выражаешь y через x и подставляешь значение y в 2x + y =12 Ответ 9

Answer 2

Calculating the Distance Vintik and Shpuntik Have to Walk Home

To calculate the distance Vintik and Shpuntik have to walk home, we need to analyze the given information and solve the problem step by step.

1. Calculate the Total Distance Traveled by Vintik and Shpuntik: - Vintik traveled 12 km in each direction. - Shpuntik traveled half the distance of Vintik in the forward direction and twice the distance in the backward direction.

2. Calculate the Total Fuel Consumption: - The car runs on syrup forward at a rate of 3 liters/km and on orange juice backward at a rate of 5 liters/km. - The total fuel available was 75 liters.

3. Determine the Remaining Fuel After Each Travel: - Calculate the fuel consumption for each leg of the journey to determine the remaining fuel.

4. Calculate the Remaining Distance and the Distance to Walk: - Use the remaining fuel to calculate the distance each character has to walk home.

Let's proceed with the calculations based on the given information.

Calculations:

1. Total Distance Traveled by Vintik and Shpuntik: - Vintik: 12 km forward + 12 km backward = 24 km - Shpuntik: 6 km forward + 24 km backward = 30 km

2. Total Fuel Consumption: - Forward: 12 km * 3 liters/km = 36 liters - Backward: 12 km * 5 liters/km = 60 liters - Total fuel used: 36 liters + 60 liters = 96 liters

3. Remaining Fuel: - Initial fuel: 75 liters - Remaining fuel: 75 liters - 96 liters = -21 liters (negative value indicates the fuel ran out before completing the journey)

4. Calculating the Distance to Walk: - Since the remaining fuel is negative, it means they ran out of fuel before completing the journey. - Vintik and Shpuntik will have to walk the entire distance back home, which is the total distance traveled by Shpuntik: 30 km.

Therefore, Vintik and Shpuntik will have to walk a distance of 30 km to return home.
