Answer 2

Calculation of the Cheapest Trip Option

To calculate the cost of the cheapest trip for a family of three from St. Petersburg to Vologda, we need to compare the cost of traveling by train and by car.

1. Train Option: - The cost of a train ticket for one person is 760 rubles. - Since there are three people in the family, the total cost of train tickets would be 760 rubles multiplied by 3, which equals 2280 rubles.

2. Car Option: - The car consumes 13 liters of gasoline per 100 km. - The distance on the highway from St. Petersburg to Vologda is 700 km. - The price of gasoline is 17 rubles per liter. - To calculate the total cost of gasoline, we need to find out how many liters of gasoline will be consumed for the entire trip and then multiply it by the price per liter. - The formula to calculate the total cost of gasoline is: (distance / 100) * fuel consumption * price per liter. - Substituting the values, we get: (700 / 100) * 13 * 17 = 1531 rubles.

Therefore, the cost of the cheapest trip for a family of three from St. Petersburg to Vologda would be 1531 rubles if they choose to travel by car.

Please note that this calculation only considers the cost of transportation and does not include other expenses such as tolls, parking fees, or maintenance costs for the car.
