Question

Из двух городов расстояние между которыми 720 км Одновременно навстречу друг другу вышли два автомобиля скорость легкового автомобиля 40 километров час скорость другого 50 километров час через сколько часов автомобили встретятся

Answer 1

1)40+50=90 км/ ч общая скорость
2) 720/90=8 ч через столько встретятся

Answer 2

Calculation of the Meeting Time between Two Cars

To calculate the time it takes for two cars to meet when they are traveling towards each other, we can use the formula:

Time = Distance / Relative Speed

In this case, the distance between the two cities is 720 km, and the speeds of the two cars are 40 km/h and 50 km/h. Let's calculate the meeting time:

1. Calculate the relative speed of the two cars: - The relative speed is the sum of the speeds of the two cars: 40 km/h + 50 km/h = 90 km/h.

2. Calculate the meeting time: - Time = Distance / Relative Speed - Time = 720 km / 90 km/h - Time = 8 hours.

Therefore, the two cars will meet after 8 hours of driving.
