Question

Нужно Решить уравнением.Автомобилю надо проехать 448км.Он ехал до остановки 4часа,после этого ему осталось проехать 192км.Какова скорость автомобиля?

Answer 1

Пусть х - скорость автомобиля 
448-192=256 км - автомобиль уже проехал, тогда составим уравнение:
256/x=4
(256-4x)/x=0
256-4x=0
4*x=256
x=256/4
x=128/2
x=64

Answer 2

Problem Statement

You have an equation that needs to be solved. An automobile needs to travel a distance of 448 km. It has already traveled for 4 hours and now needs to travel the remaining distance of 192 km. We need to find the speed of the automobile.

Solution

To find the speed of the automobile, we can use the formula:

Speed = Distance / Time

Let's calculate the time it took for the automobile to travel the initial distance of 448 km. We know that it traveled for 4 hours, so the time is 4 hours.

Now, let's calculate the speed of the automobile using the formula:

Speed = Distance / Time

For the initial distance of 448 km and the time of 4 hours, the speed is:

Speed = 448 km / 4 hours = 112 km/h.

Therefore, the speed of the automobile is 112 km/h.
