Question

Из двух городов, расстояние между которыми равно 363км, навстречу друг другу выехали два автомобиля. Через сколько часов автомобили встретятся, если их скорости равны 57км/ч и 64км/ч?

Answer 1

1)57+64=121(км ч)- скорость сближения.
2)363:121=3(ч)
Ответ:через 3 ч они встретятся.

Answer 2

363:(57+64)= 3 (ч) 
Ответ: Через 3 часа они встретятся

Answer 3

Problem Analysis

We have two cars traveling towards each other from two different cities. The distance between the cities is 363 km. The speeds of the two cars are given as 57 km/h and 64 km/h. We need to determine how many hours it will take for the cars to meet.

Solution

To find the time it takes for the cars to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two cars, as they are traveling towards each other.

Let's calculate the time it takes for the cars to meet.

Calculation

Given: - Distance between the cities = 363 km - Speed of the first car = 57 km/h - Speed of the second car = 64 km/h

Relative Speed = Speed of the first car + Speed of the second car

Relative Speed = 57 km/h + 64 km/h

Relative Speed = 121 km/h

Time = Distance / Relative Speed

Time = 363 km / 121 km/h

Time = 3 hours

Therefore, the two cars will meet after 3 hours of driving.

Answer

The two cars will meet after 3 hours of driving.
