Answer 1

46x3=138 км - расстояние которое проехал мотоцикл
46х2=92км/ч - скорость автомобиля
92х3=276 - расстояние которое проехал автомобиль 
138+276=414 - расстояние между городами

Answer 2

1) 46*2=92 км/ч скорость авто
2) 46+92=138 км/ч скорость сближения
3) 138*3=414 км расстояние между городами

Answer 3

Problem Analysis

Two friends are traveling to meet each other. One is traveling by car, and the other is traveling by motorcycle. The motorcycle's speed is 46 km/h, while the car's speed is twice as fast. After 3 hours, the friends meet. We need to find the distance between the two cities.

Solution

Let's assume the distance between the two cities is D km.

The friend traveling by motorcycle covers a distance of 46 km/h * 3 h = 138 km in 3 hours.

The friend traveling by car covers a distance of (2 * 46 km/h) * 3 h = 276 km in 3 hours.

Since they meet after 3 hours, the sum of the distances covered by both friends should be equal to the total distance between the two cities.

Therefore, we can set up the equation: 138 km + 276 km = D km.

Simplifying the equation, we find that the distance between the two cities is D = 414 km.

Answer

The distance between the two cities is **
