Question

Автомашина прошла 240 км.Их них 180 км она шла по проселочной дороге,а остальной путь - по шоссе.Расход бензина на каждые 10 км проселочной дороги составила 1,6 л,а по шоссе - на 25 % меньше.Сколько литров бензина в среднем расходовалось на каждые 10 км пути? Помогите пожалуйсто срочно решить!!!!Первому засчитаю лучший ответ**Заранее спасибо!

Answer 1

180:10*1.6=28.8
1.6-25%=1.2
60:10*1.2=7.2
28.8+7.2=36
36:240=0.15 на один км
0.15*10=1.5 на 10 км

Answer 2

Calculation of Average Fuel Consumption

To calculate the average fuel consumption for every 10 kilometers of the journey, we need to consider the fuel consumption on both the dirt road and the highway.

According to the provided information, the car traveled a total distance of 240 kilometers, with 180 kilometers on the dirt road and the remaining distance on the highway.

The fuel consumption on the dirt road was 1.6 liters for every 10 kilometers, while on the highway it was 25% less.

To calculate the fuel consumption on the highway, we need to find 25% of the fuel consumption on the dirt road and subtract it from the dirt road consumption.

Let's calculate the average fuel consumption step by step:

1. Fuel consumption on the dirt road: - Distance on the dirt road: 180 kilometers - Fuel consumption per 10 kilometers on the dirt road: 1.6 liters - Total fuel consumption on the dirt road: (180 / 10) * 1.6 = 28.8 liters.

2. Fuel consumption on the highway: - Fuel consumption on the dirt road: 28.8 liters - Fuel consumption on the highway is 25% less than on the dirt road. - Fuel consumption reduction on the highway: 25% of 1.6 liters = 0.4 liters - Fuel consumption per 10 kilometers on the highway: 1.6 - 0.4 = 1.2 liters.

Therefore, the average fuel consumption for every 10 kilometers of the journey is 1.2 liters.

Please note that these calculations are based on the provided information and assumptions made about fuel consumption. Actual fuel consumption may vary depending on various factors such as driving conditions, vehicle efficiency, and driving style.
