Question

Из города в противоположных направлениях одновременно выехали дра автомобиля.Скорость одного из них 80км/ч,а другогр - 75 км/ч.На каком расстоянии друг от друга будут автомобили через 4 ч ?

Answer 1

Скорость расхождения автомобилей 80+75=155 км/ч
Через четыре часа между ними будет 155*4=620 км

Answer 2

80×4=320
75×4=300
300+320=620

Answer 3

Problem Analysis

Two cars are traveling in opposite directions. The speed of one car is 80 km/h, and the speed of the other car is 75 km/h. We need to determine the distance between the two cars after 4 hours.

Solution

To find the distance between the two cars after 4 hours, we can use the formula:

Distance = Speed x Time

Let's calculate the distance for each car and then find the total distance between them.

1. Car 1: - Speed: 80 km/h - Time: 4 hours - Distance = 80 km/h x 4 hours = 320 km

2. Car 2: - Speed: 75 km/h - Time: 4 hours - Distance = 75 km/h x 4 hours = 300 km

To find the total distance between the two cars, we can add the distances of both cars:

Total Distance = Distance of Car 1 + Distance of Car 2

Total Distance = 320 km + 300 km = 620 km

Therefore, the two cars will be approximately 620 km apart after 4 hours.

Answer

The two cars will be approximately 620 km apart after 4 hours.
