Question

Из Вязьмы в Смоленск Выехал грузовик со скоростью 85 км/ч. Одновременно с ним из Гагарина в Москву выехала машина со скоростью 80 км/ч. Через 2 ч оба доехали. Какое расстояние от Смоленска до Москвы, если от Вязьмы до Гагарина 67 км?​

Answer 1

Ответ:

397 км

Пошаговое объяснение:

Найдём расстояние между Вязьмой и Смоленском:

85*2=170(км)-расстояние между Вязьмой и Смоленском

Найдём расстояние между Гагариным и Москвой:

80*2=160(км)-расстояние между Гагариным и Москвой

170+160+67=397(км)-расстояние между Смоленском и Москвой

Answer 2

Calculation of Distance from Smolensk to Moscow

To calculate the distance from Smolensk to Moscow, we can use the information provided about the speeds and travel times of the truck and car.

Given: - Speed of the truck from Vyazma to Smolensk: 85 km/h - Speed of the car from Gagarin to Moscow: 80 km/h - Travel time: 2 hours

We can start by calculating the distances traveled by the truck and the car separately.

The distance traveled by the truck from Vyazma to Smolensk can be calculated using the formula:

Distance = Speed × Time

Substituting the given values: Distance of truck = 85 km/h × 2 hours = 170 km

The distance traveled by the car from Gagarin to Moscow can be calculated in the same way:

Distance of car = 80 km/h × 2 hours = 160 km

Now, we need to find the total distance from Smolensk to Moscow. We know that the distance from Vyazma to Gagarin is 67 km.

Therefore, the total distance from Smolensk to Moscow can be calculated as:

Total distance = Distance of truck + Distance of car + Distance from Vyazma to Gagarin

Substituting the values: Total distance = 170 km + 160 km + 67 km = 397 km

Therefore, the distance from Smolensk to Moscow is 397 km.
