Answer 2

Calculation of the Cost of the Train Trip

To calculate the cost of the train trip for a family of 4, we need to multiply the price of a train ticket for one person by the number of people in the family. The price of a train ticket is given as 830 rubles per person.

Therefore, the cost of the train trip for the family of 4 would be: 830 rubles/person * 4 people = 3320 rubles.

Calculation of the Cost of the Car Trip

To calculate the cost of the car trip, we need to consider the distance traveled and the fuel consumption of the car.

The distance on the highway is given as 1600 km The car consumes 9 liters of gasoline per 100 km The price of gasoline is given as 21.3 rubles per liter.

To calculate the total fuel consumption for the trip, we can use the following formula: Fuel consumption = (Distance / 100) * Fuel consumption per 100 km.

Substituting the given values: Fuel consumption = (1600 km / 100) * 9 liters/100 km = 144 liters.

To calculate the cost of fuel for the trip, we can multiply the fuel consumption by the price of gasoline: Fuel cost = Fuel consumption * Price of gasoline = 144 liters * 21.3 rubles/liter.

Therefore, the cost of the car trip for this family would be: Fuel cost = 144 liters * 21.3 rubles/liter = 3067.2 rubles.

Comparison of the Costs

The cost of the train trip for the family is 3320 rubles, while the cost of the car trip is 3067.2 rubles. Therefore, the cheaper option for this family would be to take the car, as it would cost less than the train trip.

Please note that these calculations are based on the given information and may not include other factors such as tolls, parking fees, or additional expenses that may be incurred during the car trip.
