Question

Две машины выехали из двух городов одновременно на встречу друг другу. Расстояние между городами 350км. Скорость одной машины 75км|ч. Через 2 часа между машинами было 20км. Какое расстояние проехала вторая машина?

Answer 1

75*2=150
350-150=200
200-20=180
180:2=90

Answer 2

Problem Analysis

Two cars start from two cities simultaneously and travel towards each other. The distance between the cities is 350 km. After 2 hours, the distance between the cars is 20 km. We need to calculate the distance traveled by the second car.

Solution

To find the distance traveled by the second car, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by the first car in 2 hours using the given speed of 75 km/h:

Distance1 = Speed1 × Time1 = 75 km/h × 2 hours = 150 km

Now, we can calculate the distance traveled by the second car. Since the total distance between the cars is 350 km and the distance between them after 2 hours is 20 km, the distance traveled by the second car is:

Distance2 = Total Distance - Distance1 - Distance between the cars = 350 km - 150 km - 20 km = 180 km

Therefore, the second car has traveled a distance of 180 km.

Answer

The second car has traveled a distance of 180 km.
