Question

Из двух городов одновременно навстречу друг другу выехали машина со скоростью 66 км/ч и велосипедист со скоростью 18 км/ч. Через 3 часа им осталось проехать до встречи 46 км. Вычислите расстояние между городами.

Answer 1

1)66+18=84км\ч-скорость сближения.
2)84*3=252км-проехали за 3 ч.
3)252+46=298км-расстояние между городами.

Answer 2

Problem Analysis

We are given that a car and a cyclist start simultaneously from two different cities towards each other. The car has a speed of 66 km/h, and the cyclist has a speed of 18 km/h. After 3 hours, they have 46 km left to meet. We need to calculate the distance between the two cities.

Solution

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

The car travels at a speed of 66 km/h for 3 hours, covering a distance of 66 * 3 = 198 km.

The cyclist travels at a speed of 18 km/h for 3 hours, covering a distance of 18 * 3 = 54 km.

The remaining distance between them is 46 km.

So, the total distance between the two cities is:

D = distance covered by the car + distance covered by the cyclist + remaining distance

D = 198 km + 54 km + 46 km

D = 298 km

Therefore, the distance between the two cities is 298 km.

Answer

The distance between the two cities is 298 km.
