Question

Два автомобиля из двух пунктов вышли навстречу друг другу скорость первого автомобиля 96 км/ч а скорость второго на 19 км/ч меньше через 4 часа расстояние между ними стало 49 км какое расстояние было между пунктами в начале движение?

Answer 1

Скорость второго 96-19=77
Расстояние 49+(96×4"то что проехал первый")+(77×4"то что проехал второй")=49+384+308=741км

Answer 2

Problem Analysis

To solve this problem, we need to find the initial distance between the two points before the cars started moving towards each other. We are given the speed of the first car, the speed of the second car, and the time it took for the distance between them to become 49 km.

Given Information

- Speed of the first car: 96 km/h - Speed of the second car: 96 km/h - 19 km/h = 77 km/h - Time taken for the distance between them to become 49 km: 4 hours

Solution

Let's denote the initial distance between the two points as D.

The total distance covered by both cars in 4 hours is 96 km/h * 4 h + 77 km/h * 4 h = 384 km + 308 km = 692 km.

We can use the formula: distance = speed * time to find the initial distance between the two points.

So, D = 692 km.

Therefore, the initial distance between the two points in the beginning was 692 km.
